Managing Joint Pain
Joint pain (arthralgia) is one of the most common symptoms seen in general practice. It ranges from a mild ache after exercise to severe inflammation that prevents normal movement. The cause matters, because treatment for osteoarthritis is completely different from treatment for rheumatoid arthritis or gout.
A focused history, physical examination, and targeted blood tests can usually identify the type of joint problem within a single consultation. Getting the diagnosis right early makes a real difference — particularly with inflammatory conditions like rheumatoid arthritis, where treatment within three months of onset significantly improves long-term outcomes.
Seek same-day medical advice if:
- A single joint is hot, red, and very swollen (possible septic arthritis)
- You have joint swelling with a fever
- You cannot bear weight on the affected joint after an injury
- The joint looks deformed or is locked in one position
A hot, swollen joint with fever could be septic arthritis — a medical emergency. Delayed treatment risks permanent joint damage.
Common causes
Osteoarthritis
The most common joint condition in the UK, affecting over 8.75 million people. Cartilage gradually thins, and the bone beneath remodels, causing pain, stiffness, and reduced range of motion. It most commonly affects knees, hips, hands, and the base of the thumb. Pain typically worsens with activity and eases with rest. Morning stiffness lasts less than 30 minutes, which helps distinguish it from inflammatory arthritis.
Rheumatoid arthritis
An autoimmune condition where the immune system attacks the joint lining (synovium), causing inflammation, swelling, and eventual joint erosion. It typically presents with symmetrical swelling of the small joints in the hands and feet, prolonged morning stiffness (over 30 minutes), and fatigue. Early treatment with DMARDs (disease-modifying anti-rheumatic drugs) can prevent joint damage. NICE recommends starting treatment within three months of symptom onset.
Gout
Caused by uric acid crystals depositing in a joint, gout produces sudden, severe pain — classically in the big toe, though it can affect any joint. The joint becomes red, hot, and exquisitely tender. Attacks typically last 5-7 days. Blood uric acid levels are helpful between attacks but can be misleadingly normal during a flare.
Mechanical and soft tissue causes
Tendinitis, bursitis, ligament sprains, and overuse injuries account for a large proportion of joint pain, particularly in younger, active people. The pain is usually localised to a specific area around the joint rather than within it. These conditions generally respond well to rest, physiotherapy, and anti-inflammatory medication.
Diagnosis
The clinical history provides the most important clues: which joints are affected, the pattern of symptoms (morning stiffness, relationship to activity), speed of onset, and family history. Examination assesses for swelling, warmth, tenderness, range of motion, and deformity.
Blood tests help distinguish between types. Inflammatory markers (CRP, ESR) are raised in rheumatoid arthritis and gout but normal in osteoarthritis. Rheumatoid factor and anti-CCP antibodies point toward RA. Uric acid is checked if gout is suspected.
X-rays may show joint space narrowing (osteoarthritis) or erosions (rheumatoid arthritis). Ultrasound is increasingly used to detect early synovitis and guide joint aspiration when fluid needs to be sampled.
How we can help
We offer same-day GP consultations for joint pain with on-site blood testing. A comprehensive joint pain panel covers inflammatory markers, rheumatoid factor, anti-CCP, uric acid, and basic metabolic screen. Results are typically available within 24-48 hours.
If specialist input is needed, we refer directly to rheumatologists, orthopaedic surgeons, or sports medicine consultants — usually with an appointment within days. For acute gout or flares of inflammatory arthritis, treatment can begin the same day.

Q.What blood tests are done for joint pain?
A standard joint pain blood panel includes ESR and CRP (inflammation markers), rheumatoid factor and anti-CCP antibodies (for rheumatoid arthritis), uric acid (for gout), full blood count, and liver and kidney function. If autoimmune disease is suspected, an ANA (antinuclear antibody) test may be added. Results help distinguish inflammatory joint disease from mechanical causes like osteoarthritis.
Q.What's the difference between osteoarthritis and rheumatoid arthritis?
Osteoarthritis is a wear-and-repair condition affecting cartilage, most common after age 45, and typically affects weight-bearing joints and the hands. Pain worsens with activity and improves with rest. Rheumatoid arthritis is an autoimmune disease that can start at any age, causes joint inflammation and swelling (especially in the small joints of the hands and feet), and is typically worst in the morning with stiffness lasting over 30 minutes.
Q.When is joint pain an emergency?
A single hot, red, swollen joint — especially the knee — with fever needs same-day assessment to rule out septic arthritis (joint infection). Untreated, septic arthritis can destroy a joint within days. Gout can look similar but is less dangerous. Only a doctor can reliably distinguish between them, sometimes requiring joint aspiration (removing fluid with a needle for analysis).
Q.Should I exercise with joint pain?
Yes, in most cases. NICE strongly recommends regular exercise for both osteoarthritis and rheumatoid arthritis. Strengthening the muscles around a joint reduces load on the joint itself. Low-impact activities — swimming, cycling, walking — are easiest to tolerate. A physiotherapist can design a programme suited to which joints are affected. Complete rest tends to make joint stiffness and pain worse, not better.
Q.Can diet affect joint pain?
For gout, absolutely. Reducing alcohol, sugary drinks, and purine-rich foods (red meat, offal, shellfish) lowers uric acid and prevents flares. For other types of arthritis, maintaining a healthy weight is the most impactful dietary factor — every kilogram of excess body weight adds roughly 4 kg of force across the knee joint. Anti-inflammatory diets (Mediterranean-style) may help modestly but are not a substitute for medical treatment.
