Rheumatoid Arthritis

Medical terms: RA • Autoimmune Inflammatory Arthritis • Rheumatoid Synovitis

Rheumatoid arthritis is a long-term autoimmune disease in which inflammation targets the joint lining, called the synovium. It commonly causes persistent swelling, warmth, pain and prolonged morning stiffness in the small joints of the hands, wrists or feet, although its pattern varies and other joints or organs can be involved.

Early treatment can suppress inflammation and reduce permanent joint damage. Referral should not wait for a positive rheumatoid factor, anti-CCP result or raised inflammation marker when persistent synovitis is suspected. A suddenly hot joint, fever, serious infection symptoms, painful red eye, new breathing difficulty or spinal-cord symptoms needs urgent assessment rather than routine flare advice.

A flare is not the only reason an RA patient can become unwell

Seek Urgent Medical Help for These Warning Signs

  • One joint becomes suddenly very painful, hot, red and swollen, especially with fever, chills, confusion or feeling seriously unwell.
  • Fever, rigors, severe sore throat, new rash, persistent cough, painful urination or rapidly worsening illness while taking immune-modifying medicine.
  • New breathlessness, chest pain, coughing blood, blue lips, collapse or rapidly falling exercise tolerance.
  • A painful red eye, light sensitivity, reduced vision, new floaters or sudden visual loss.
  • New neck pain with unsteadiness, clumsy hands, limb weakness, spreading numbness or bladder or bowel change.
  • A sudden snap followed by loss of finger or wrist movement, rapidly increasing numbness, or a cold pale hand or foot.
  • Vomiting blood, black stools, severe abdominal pain or fainting while using anti-inflammatory medicine or steroids.
  • An accidental daily rather than weekly dose of a prescribed DMARD, or any suspected overdose.

Infection can progress with less obvious fever in someone taking immunosuppressive medicine, and septic arthritis can resemble a flare. Do not inject, massage or simply increase steroid medicine for a newly hot swollen joint without urgent clinical advice.

What Happens in Rheumatoid Arthritis?

Immune activation The immune system mistakenly maintains inflammation against the body’s own tissues.
Synovitis The joint lining thickens and becomes inflamed, producing swelling, warmth, pain and stiffness.
Cartilage and bone damage Uncontrolled inflammation can erode bone and damage cartilage, changing alignment and function.
Tendons and bursae Inflammation can affect tendon sheaths and bursae, causing triggering, instability or rarely tendon rupture.
Systemic disease Inflammation may affect energy, blood, skin, eyes, lungs, heart, blood vessels or nerves.
Flares and remission Disease activity can rise and fall; modern treatment aims for sustained remission or low activity.

RA is not caused by a joint being “worn out,” and it is not contagious. Genes, smoking and other environmental or hormonal factors influence risk, but most people cannot identify one event that caused the disease.

What Does the Usual Joint Pattern Look Like?

Hands and knuckles MCP and PIP joints may feel soft, swollen and tender; finger-end DIP joints are less typical for RA.
Wrists Pain, swelling, reduced movement and grip weakness are common; synovitis can contribute to carpal-tunnel symptoms.
Feet and forefeet MTP swelling may cause pain under the ball of the foot, difficulty walking or a feeling of stepping on pebbles.
Larger joints Knees, ankles, elbows and shoulders can be involved; hip disease is possible but less visible on examination.
Both sides A broadly symmetrical pattern is common, but early RA can begin in only a few joints or look uneven.
Cervical spine Long-standing disease can affect upper-neck stability; RA does not typically inflame the lower back in the same way.

Pattern recognition helps but is not a diagnostic rule. RA can begin gradually or quickly, and palindromic attacks may settle completely between episodes before persistent disease develops in some people.

Symptoms That Suggest Inflammatory Arthritis

  • Visible or palpable soft swelling in one or more joints rather than pain alone.
  • Morning stiffness commonly lasting longer than 30 to 60 minutes and improving with movement.
  • Stiffness after rest, difficulty making a fist, reduced grip or pain under the forefoot.
  • Symptoms involving several joints, often including the small joints of hands or feet.
  • Persistent symptoms across weeks rather than a brief strain that steadily settles.
  • Fatigue, low-grade fever, reduced appetite, weight change or a general unwell feeling.
  • Flares alternating with periods of much lower disease activity.

Absence of symmetry, normal blood tests or pain in only one joint does not safely exclude early RA. Conversely, pain in many joints without objective synovitis has several other possible causes and should not be labelled RA from symptoms alone.

Why Early Referral Matters

NICE recommends specialist referral for any adult with suspected persistent synovitis of undetermined cause. Referral is urgent when the small joints of the hands or feet are affected, more than one joint is involved, or symptoms began at least three months before medical advice was sought—even if CRP or ESR is normal and rheumatoid factor or anti-CCP is negative.

Do not wait for every result Primary-care tests and X-rays can be arranged, but they should not delay a rheumatology opinion.
Inflammation can damage early Structural damage may begin in the first years, sometimes before a plain X-ray becomes abnormal.
DMARDs need specialist planning Disease-modifying medicine is most useful when started promptly and monitored appropriately.
Diagnosis may evolve Early inflammatory arthritis can need repeat examination as its pattern and response become clearer.

RA, Osteoarthritis or Another Condition?

Osteoarthritis Often causes activity-related pain, brief after-rest stiffness and bony enlargement; OA and RA can coexist.
Psoriatic arthritis May accompany psoriasis, nail pitting, whole-digit swelling or tendon-insertion pain and can affect DIP joints.
Lupus or connective-tissue disease Joint symptoms may occur with rashes, mouth ulcers, Raynaud symptoms, blood-count changes or organ involvement.
Gout or CPP crystal arthritis Often produces sudden intense attacks; crystals on joint-fluid analysis do not completely exclude simultaneous infection.
Viral or reactive arthritis Timing around infection, rash, fever, bowel or urinary symptoms may change the investigation.
Fibromyalgia or widespread pain Can cause severe tenderness, fatigue and poor sleep without synovitis, and can also coexist with controlled RA.

How Is Rheumatoid Arthritis Diagnosed?

History Joint distribution, swelling, stiffness duration, symptom timeline, flares, fatigue, skin, eye, lung and family history.
Joint examination The clinician looks and feels for synovitis, movement loss, tendon involvement, nodules, deformity and functional impact.
Blood tests RF, anti-CCP, CRP, ESR and blood count support the assessment; kidney and liver tests help with alternatives and treatment planning.
Imaging Hand and foot X-rays establish a baseline; ultrasound or MRI may show synovitis or erosions in selected uncertain cases.
Joint fluid Aspiration may be essential in an acutely hot or unexplained swollen joint to assess infection and crystals.
Specialist synthesis No single result proves or excludes RA; diagnosis combines examination, pattern, time course, tests and imaging.

Classification scores such as the 2010 ACR/EULAR criteria help create consistent groups for clinical practice and research, but they do not replace expert diagnosis or justify delaying referral until a particular number is reached.

Understanding Rheumatoid Blood Tests

Rheumatoid factor—RF Present in many people with RA, but it can be negative in RA and positive in healthy people or other conditions.
Anti-CCP antibody Supports RA and can indicate higher radiographic-progression risk, but a negative result does not rule disease out.
CRP and ESR General inflammation markers useful for context and monitoring; either can be normal despite active synovitis.
Full blood count May show anaemia or another blood-cell abnormality and provides a baseline before some medicines.
Kidney and liver profile Helps assess overall health and whether selected anti-inflammatory or disease-modifying medicines are suitable.
Seronegative RA RA without detectable RF and anti-CCP; the diagnosis still requires a compatible clinical inflammatory pattern.

A positive antibody in someone without synovitis is not a diagnosis by itself. Likewise, treatment should not be withheld from clinically convincing inflammatory arthritis solely because antibody or inflammation tests are normal.

What Can Imaging Show?

Plain X-ray May show soft-tissue swelling, periarticular bone thinning, uniform joint-space loss, marginal erosions or later deformity.
Ultrasound Can demonstrate synovial thickening, fluid, power-Doppler activity, tenosynovitis and some erosions.
MRI Can show synovitis, tenosynovitis, bone-marrow oedema and erosions before they are obvious on X-ray in selected cases.
Limitations Imaging findings are not unique to RA and must match the clinical picture; an early normal X-ray does not exclude RA.

NICE does not recommend routine ultrasound simply to monitor established disease activity. Clinical disease scores, blood tests, function and specialist assessment usually guide treat-to-target decisions.

Common Report and Clinic Terms

Synovial hypertrophy Thickened joint lining; Doppler activity helps describe current blood flow but is not interpreted alone.
Tenosynovitis Inflammation around a tendon within its sheath, commonly seen around the wrist, hand or ankle.
Marginal erosion A focal loss of bone near the joint margin associated with inflammatory joint damage.
Power-Doppler signal Blood-flow signal within synovium that may support active inflammation in the correct setting.
DAS28 A composite disease-activity score using 28 joints plus inflammation and patient assessment; it has limitations.
HAQ A questionnaire that measures how the condition affects daily function rather than only inflammation.
Remission or low disease activity Treatment targets indicating inflammation is absent or suppressed to a low level—not necessarily that every pain has vanished.

What Does “Treat to Target” Mean?

  1. Agree the target Usually remission; low disease activity may be the practical target when remission cannot be achieved.
  2. Start disease-modifying treatment promptly A conventional DMARD is selected according to disease, health, pregnancy plans, risk and patient preference.
  3. Measure response Symptoms, swollen and tender joints, CRP, function and a composite activity score are reviewed regularly.
  4. Adjust when target is not met Dose escalation, combination therapy or another DMARD mechanism may be considered by rheumatology.
  5. Maintain and monitor Even in remission, medicine safety, function, comorbidities, vaccination and flare access remain important.

Painkillers and injections may reduce symptoms but do not replace disease-modifying therapy. Some pain may persist after inflammation is controlled because of prior damage, osteoarthritis, tendon disease, altered mechanics or pain sensitisation; simply escalating immune therapy is not always the answer.

Understanding RA Medicines

Conventional DMARDs Conventional disease-modifying medicines can suppress disease activity and reduce future damage.
Biological DMARDs Target specific immune pathways and are considered when disease remains active despite suitable conventional treatment.
Targeted synthetic DMARDs Oral medicines such as JAK inhibitors act on intracellular pathways and require individualized risk assessment.
Glucocorticoids May be used briefly as bridging treatment or for flares; prolonged use carries infection, bone, glucose and other risks.
NSAIDs and analgesics Can help pain and stiffness in selected patients but do not prevent erosions or replace a DMARD.
Joint injection May help one persistently inflamed joint after infection is excluded, while the overall disease plan is reviewed.

DMARD choice and sequence belong with a rheumatology team. Do not start, stop, double or share these medicines based on a website, and do not use a leftover steroid course to treat a presumed flare without advice.

DMARD Dosing and Monitoring Safety

  • Some RA medicines are taken once weekly—not daily, sometimes with a prescribed supplement on a separate schedule.
  • Regular blood counts and liver and kidney tests are needed; frequency changes with treatment stage, dose and local protocol.
  • Mouth ulcers, unusual bruising, severe sore throat, fever, jaundice or new persistent cough and breathlessness require prompt advice.
  • Some antibiotics and other medicines interact. Tell every prescriber and pharmacist that a DMARD is being taken.
  • Pregnancy and conception plans must be discussed before treatment; several RA medicines require advance specialist changes.
  • Alcohol advice depends on medicine, liver risk and local policy; obtain an individual plan.

If a medicine prescribed once weekly has accidentally been taken daily, seek emergency medical advice immediately even if the person initially feels well. Do not wait for the next scheduled blood test.

Infection, Vaccines, Surgery and Pregnancy

Before immune treatment Baseline bloods and screening for infections such as tuberculosis or hepatitis may be needed, depending on the medicine.
Vaccination Vaccines should be reviewed early. Some live vaccines are unsuitable during certain immune-suppressing treatments.
During infection Contact the treating team promptly for fever or significant infection and follow the medicine-specific sick-day plan.
Before surgery The surgeon and rheumatologist coordinate which medicines continue or pause and exactly when they restart.
Pregnancy and breastfeeding Many people can have successful pregnancies, but disease control and medicine compatibility require preconception planning.

There is no safe universal “stop all DMARDs” instruction. Unplanned interruption can cause a flare, while continuing an unsuitable medicine can also be dangerous. Obtain a named, medicine-specific plan from the prescribing team.

Flares: What to Do and What Not to Miss

  1. Use the agreed flare route Contact the rheumatology or treating team early if swelling, stiffness and function are worsening.
  2. Check for a changed pattern One very hot joint, fever, cough, urinary symptoms or recent procedure raises concern for infection.
  3. Pace temporarily Reduce heavy load, use short rest periods and preserve gentle movement rather than prolonged bed rest.
  4. Follow the prescribed plan Use only agreed analgesic, anti-inflammatory or short-term steroid instructions and continue monitoring.
  5. Review the disease strategy Repeated flares may mean the DMARD plan or another source of pain needs reassessment.

Exercise, Therapy and Joint Protection

Physiotherapy Maintains movement, strength, aerobic fitness, balance and confidence with activity adapted to disease state.
Occupational therapy Supports hand function, joint protection, fatigue management, work adaptation and assistive devices.
Hand exercise Can improve function when tailored; a highly inflamed or unstable joint may need temporary modification.
Foot care Appropriate footwear, podiatry, insoles or pressure relief can protect painful or deformed feet.
Splints May support selected painful or unstable joints, but fit and duration matter to avoid stiffness or pressure injury.
General health Smoking cessation, cardiovascular risk care, sleep, vaccination and bone health are part of RA management.

Exercise does not replace a DMARD, but controlled inflammation plus progressive movement offers the best chance of preserving capacity. During a flare, the programme is adjusted rather than abandoned indefinitely.

RA Beyond the Joints

Eyes and mouth Dryness may occur with secondary Sjögren disease; painful redness or visual change needs urgent eye assessment.
Lungs RA or its medicines can be associated with pleurisy, infection or interstitial lung disease; new breathlessness must be assessed.
Heart and circulation Chronic inflammation increases cardiovascular risk, so blood pressure, cholesterol, diabetes and smoking matter.
Skin and vessels Rheumatoid nodules can occur; unusual ulcers, purple spots or painful nerve symptoms may suggest vasculitis.
Blood and bone Anaemia, medicine-related blood-count changes and osteoporosis risk require appropriate monitoring.
Nerves and tendons Carpal tunnel, other compression neuropathies, tendon damage and cervical myelopathy need targeted assessment.

When Is an Orthopaedic or Surgical Opinion Needed?

Rheumatology controls the inflammatory disease. Orthopaedic and hand teams help when a local structural problem persists despite optimized medical and rehabilitation care, or when delay risks irreversible damage.

  • Persistent pain from joint damage or an identifiable tendon or soft-tissue problem.
  • Worsening function, progressive deformity or persistent localized synovitis despite suitable treatment.
  • Actual or threatened tendon rupture, nerve compression such as carpal tunnel, or a stress fracture.
  • Suspected septic arthritis, which needs urgent combined medical and surgical treatment.
  • Cervical myelopathy symptoms, which require urgent MRI and specialist spinal assessment.

SR Speciality Hospital does not perform joint replacement, spine surgery or complex reconstruction. Patients who need these procedures are referred to an appropriate higher centre while medical disease control and rehabilitation are coordinated.

Common Myths About Rheumatoid Arthritis

Myth RA is ordinary age-related arthritis.
Fact RA is an autoimmune inflammatory disease and can begin at many ages.
Myth A negative rheumatoid factor rules it out.
Fact Seronegative RA exists; examination and the whole pattern remain essential.
Myth A positive rheumatoid factor proves RA.
Fact RF may be positive in other conditions or in people who never develop RA.
Myth Painkillers protect the joints.
Fact They may ease symptoms, but disease-modifying medicine is needed to control autoimmune inflammation.
Myth Feeling better means the DMARD can be stopped.
Fact Remission often reflects effective treatment; any reduction must be cautious and specialist-led.
Myth Exercise always worsens inflamed joints.
Fact Activity is adapted during flares, while appropriate ongoing exercise helps preserve strength and function.

Frequently Asked Questions

Is rheumatoid arthritis the same as osteoarthritis?

No. RA is an autoimmune inflammatory disease; OA is a whole-joint degenerative condition. A person can have both.

Can RA start in only one joint?

Yes. Although several symmetrical small joints are typical, early disease can begin in one or a few joints and evolve over time.

Does a normal CRP or ESR exclude RA?

No. Normal inflammation markers do not exclude persistent synovitis and should not delay an indicated rheumatology referral.

What is seronegative rheumatoid arthritis?

RA diagnosed from a compatible inflammatory clinical picture despite negative RF and anti-CCP tests.

Can a positive rheumatoid factor occur without RA?

Yes. RF can occur in other illnesses and in some healthy people. It must be interpreted with symptoms and examination.

Will an early X-ray be normal?

It may be. X-rays can establish a baseline and exclude alternatives, but early inflammatory change may not yet be visible.

Can ultrasound diagnose RA?

Ultrasound can show synovitis, tenosynovitis, Doppler activity and some erosions, but these findings do not diagnose RA without the clinical context.

What is a DMARD?

A disease-modifying antirheumatic drug suppresses disease activity and helps prevent damage rather than only relieving pain.

How quickly do DMARDs work?

Many take weeks or months. Short-term bridging treatment may be considered while a new DMARD takes effect, with appropriate monitoring.

Are some DMARDs also used in cancer care?

Yes, but cancer and rheumatoid-arthritis regimens can use very different doses, schedules, goals and monitoring. Follow only the plan written for the individual patient.

Should I stop my DMARD if I get an infection?

Follow the medicine-specific sick-day plan and contact the prescribing team promptly. Do not apply a universal stop rule to every drug or infection.

Can I receive vaccines while taking RA medicine?

Often yes, and vaccination is important, but timing and live-vaccine suitability depend on the medicine and immune status.

Can I exercise during a flare?

Usually gentle movement is preserved while heavy load is reduced. A physiotherapist or treating team can adapt the plan to the joint and flare severity.

Can diet cure rheumatoid arthritis?

No diet replaces DMARD therapy. A balanced Mediterranean-style pattern can support general and cardiovascular health.

Can rheumatoid arthritis go into remission?

Yes. Modern treat-to-target care can achieve remission or low disease activity, but ongoing review and often continued treatment remain important.

A Note From Our Doctors

The information on this page is intended to help you understand your condition. It should not be considered a diagnosis or a substitute for a consultation with a qualified medical professional.

Every patient is unique. The same symptom can have different causes in different individuals, and the most appropriate investigations and treatment depend on your medical history, examination findings, age, existing medical conditions and test results.

At SR Speciality Hospital, we believe in treating the whole patient—not just a symptom, scan or laboratory report. Every treatment plan is individualised after careful medical evaluation.

Orthopaedic Consultation

Are swollen joints and morning stiffness affecting hand use, walking or work?

Bring all previous blood results, X-rays, ultrasound or MRI reports and a complete medicine list. Note which joints swell, how long morning stiffness lasts, when symptoms began, infection or pregnancy concerns and any eye, breathing, nerve or neck symptoms.
