Arthritis Symptoms: Types, Causes, and What Helps

"Arthritis" is a single word that covers more than 100 different joint conditions. It's the leading cause of disability in older adults globally, and in India, it is ubiquitous — affecting an estimated 180–200 million people, with numbers growing as the population ages and metabolic risk factors (obesity, diabetes) become more prevalent.

The word comes from the Greek arthron (joint) and itis (inflammation). But not all arthritis is inflammatory — osteoarthritis, the most common form, involves joint degeneration as much as inflammation. Understanding which type of arthritis you have is the first step to managing it correctly, because the treatments are different and in some cases quite specific.

The Main Types of Arthritis in India

Osteoarthritis (OA)

The most common form. Affects at least 100 million Indians, with a significant proportion undiagnosed. Osteoarthritis is a disease of joint cartilage deterioration — the smooth surface that covers the bone ends in joints wears away over time, leaving bones to rub against each other.

Most commonly affected joints: knees (by far the most common site in India), hips, fingers, thumbs, and the lumbar and cervical spine. Shoulder and ankle OA are less common.

Risk factors:

• Age — the most significant risk factor. OA increases dramatically after 50.
• Female sex — women have higher rates of knee and hand OA
• Excess body weight — each kg of excess weight adds 3–5 kg of force across the knee per step
• Previous joint injury — post-traumatic arthritis after a ligament tear, fracture, or meniscus injury
• Repetitive joint loading — squatting, kneeling, or impact-heavy occupations
• Family history
• Joint alignment problems (knock knees, bow legs)

Symptoms of osteoarthritis:

• Deep, aching joint pain — typically described as a dull ache rather than sharp
• Worsens with activity and weight-bearing; improves with rest (contrast with rheumatoid arthritis)
• Morning stiffness that resolves within 30 minutes (contrast with rheumatoid: more than 1 hour)
• Stiffness after being in one position for a while (the "gelling phenomenon") that loosens with movement
• Crepitus — a grinding, crackling, or creaking sensation or sound with joint movement
• Joint swelling — from fluid accumulation (effusion) or bony enlargement
• Decreased range of motion
• In advanced knee OA: difficulty climbing stairs, walking long distances, rising from a chair

What's happening structurally: the articular cartilage thins and develops fissures. The underlying bone tries to compensate by thickening (sclerosis) and forming new bone at the joint margins (osteophytes or bone spurs). These osteophytes are visible on X-ray and are the characteristic feature of OA.

Rheumatoid Arthritis (RA)

An autoimmune disease in which the immune system attacks the synovium — the lining of the joint. This causes chronic inflammation that, if untreated, erodes cartilage and bone and can lead to permanent joint deformity. Affects 0.5–1% of the Indian population — approximately 7–10 million people.

Key features that distinguish RA from OA:

• Bilateral symmetry: RA almost always affects the same joints on both sides simultaneously — both wrists, both knuckles, both ankles, both knees. OA may be asymmetric.
• Small joint involvement: RA typically begins in the small joints — metacarpophalangeal joints (knuckles), proximal interphalangeal joints (middle finger joints), and wrists. OA more commonly affects the distal interphalangeal joints (furthest finger joints) and weight-bearing joints.
• Morning stiffness lasting more than 1 hour: this is a characteristic of inflammatory arthritis. The stiffness in OA resolves within 30 minutes; RA stiffness can last 2–4 hours or the entire morning.
• Systemic symptoms: RA is a systemic disease — fatigue, low-grade fever, weight loss, and a general sense of feeling unwell accompany the joint symptoms. OA is purely local.
• Soft joint swelling: in RA the joints feel soft and boggy (from synovial tissue proliferation) rather than the firm, bony enlargement of OA.
• Rheumatoid nodules: firm lumps under the skin, particularly near the elbows, in some patients with RA.

Blood markers: rheumatoid factor (RF) is positive in about 70–80% of RA patients. Anti-CCP (anti-cyclic citrullinated peptide) antibody is more specific — positive in 60–70% and highly diagnostic. CRP and ESR (inflammatory markers) are typically elevated. Not all RA patients are positive for RF or anti-CCP — "seronegative RA" exists.

RA requires early, aggressive treatment with disease-modifying antirheumatic drugs (DMARDs) — primarily methotrexate. Delaying treatment allows joint destruction to occur that cannot be reversed. Biological agents (adalimumab, rituximab) are used for disease not controlled by conventional DMARDs. Early rheumatology referral is essential.

Gout

Covered in detail in the dedicated gout blog. Gout is a form of inflammatory arthritis caused by monosodium urate crystal deposition in joints, resulting from sustained hyperuricaemia. Presents as sudden, intensely painful joint inflammation — classically the big toe, but also ankles, knees, and wrists. Managed with uric acid-lowering therapy alongside anti-inflammatory treatment of attacks.

Psoriatic Arthritis

An inflammatory arthritis associated with the skin condition psoriasis (affecting approximately 30% of psoriasis patients). A variable condition that can affect any joint. Characteristic features include:

• "Sausage digits" — dactylitis (swelling of an entire finger or toe)
• Nail changes — pitting, separation, thickening (psoriatic nail disease)
• Asymmetric joint involvement (unlike RA)
• Sacroiliac joint involvement in some patients
• Association with visible psoriasis plaques (though in some patients arthritis precedes skin disease)

Requires rheumatology management.

Ankylosing Spondylitis (Axial Spondyloarthritis)

A form of inflammatory arthritis primarily affecting the sacroiliac joints and spine. Most common in young men (onset typically 20–40 years). Classic features:

• Chronic lower back pain and stiffness — worse with rest, improved with exercise (the opposite of OA)
• Morning stiffness lasting more than 1 hour
• Back pain at night that improves with activity
• Reduced spinal mobility
• Associated with other features: inflammatory eye disease (uveitis — red, painful eye), inflammatory bowel disease
• HLA-B27 genetic marker positive in 90% of patients

Long-standing untreated ankylosing spondylitis leads to fusion of the vertebrae — the "bamboo spine" appearance on X-ray. Early treatment with NSAIDs, physiotherapy, and biologics (anti-TNF agents) when needed significantly reduces this progression.

Reactive Arthritis

Joint inflammation triggered by an infection elsewhere in the body — typically a gastrointestinal infection (Salmonella, Shigella, Campylobacter) or a urogenital infection (Chlamydia). Asymmetric, large joint involvement. Often self-limiting within 3–6 months.

Septic Arthritis (Infectious Arthritis)

Direct bacterial infection of a joint. Medical emergency. Presents with sudden, severe joint pain, swelling, warmth, redness, and fever. Most commonly affects the knee in adults. Requires immediate hospitalisation, IV antibiotics, and often joint drainage. If not treated promptly, can destroy the joint within days.

Any hot, red, acutely swollen joint with fever is septic arthritis until proven otherwise.

General Symptoms That May Indicate Arthritis

The pattern varies by type, but common presentations:

Pain — most arthritis presents with joint pain. The character, timing, and distribution of pain are diagnostic clues.

Swelling — visible joint enlargement, either from fluid, soft tissue proliferation, or bony changes.

Stiffness — particularly morning stiffness. Duration and time of day are diagnostically important.

Warmth and redness — more prominent in inflammatory arthritis (RA, gout, reactive, septic); less in OA.

Reduced range of motion — limited ability to fully bend, straighten, or rotate the joint.

Crepitus — grinding, clicking, or crackling with movement.

Deformity — in advanced or untreated RA: ulnar deviation of the fingers, swan-neck or boutonnière finger deformities. In OA: bony nodules on finger joints (Heberden's nodes at distal joints, Bouchard's nodes at middle joints).

Systemic features — fatigue, weight loss, fever (RA, psoriatic, reactive arthritis, septic).

Diagnosis

Blood tests: rheumatoid factor, anti-CCP, uric acid, CRP, ESR, ANA (antinuclear antibody), complete blood count. The panel selected depends on the clinical picture.

X-ray: shows bone and joint space changes. OA: narrowed joint space, osteophytes, subchondral sclerosis. RA: periarticular osteopenia, joint erosions (in later stages). Ankylosing spondylitis: sacroiliac joint changes.

Ultrasound: shows soft tissue changes (synovitis, effusion, erosions) not visible on X-ray. Useful for diagnosis and guiding joint injections.

MRI: for detailed soft tissue assessment and early inflammatory changes.

Joint fluid aspiration: for acute swollen joint — fluid appearance and culture diagnose gout (crystals), septic arthritis (bacteria), and RA (inflammatory cells).

Management Principles

Osteoarthritis:

• Weight loss — the most impactful intervention for knee OA
• Exercise — strengthening the muscles around the affected joint reduces pain and improves function; physiotherapy guidance is valuable
• Paracetamol and topical NSAIDs for pain
• Oral NSAIDs for more significant pain (with gastric protection)
• Intra-articular steroid injection — temporary relief for active inflammation
• Intra-articular hyaluronic acid — modest evidence for some benefit in knee OA
• Joint replacement surgery — for severe end-stage OA unresponsive to conservative management

Rheumatoid arthritis:

• Early DMARD therapy — methotrexate is the cornerstone. Start as early as possible.
• Biological agents (anti-TNF, anti-IL-6, anti-CD20) for inadequate DMARD response
• Low-dose corticosteroids as a bridge while DMARDs take effect
• Physiotherapy and occupational therapy for joint protection
• Regular monitoring for medication side effects and disease progression

Gout: uric acid-lowering therapy (allopurinol, febuxostat) and dietary modification. See dedicated gout blog.

Ankylosing spondylitis: daily physiotherapy and exercise (absolutely central — the disease fuses joints, and movement prevents this), NSAIDs, biologics when needed.
