Like the picture on the pain page, this man has helpfully managed to get a red glow in the areas of pain. Less helpfully, all his skin has fallen off and he is dead. It can be very difficult to treat joint tenderness in deceased patients, although some alternative therapies claim to be able to cure this. Obviously, they can't.


Pain and swelling, in joints.



Joint pain especially is incredibly common. Joint swelling is less so, but the two are almost always related.


The pain can come from many causes; in destructive disease, its from nerve ending being exposed by damage to bone and cartilage, in non destructive conditions, I'm not sure where the pain comes from.

Clinical and Associated Features

The symptoms of joint pain will vary according to the cause. Symptoms like pain, swelling, stiffness, or warmth suggest joint inflammation.

May also be:

  • redness,
  • painful to touch
  • reduced joint mobility.

To separate rheumatoid and osteoarthritis, Rheumatoid arthritis is classically stiff and painful in the morning, getting looser and less painful as they move through the day. Osteoarthritis may not present with stiffness, and gets worse throughout the day.

Differential Diagnosis




Others (less common):

  • Allergic reaction - commonly to things like nuts, milk, caffeine, etc.
  • Chronic Fatigue Syndrome
  • Leukaemia


Firstly check for inflammatory markers - ESR and CRP. Along with this, go for Rheumatoid factor. It's not very helpful often, but it can separate inflammatory conditions into seronegative and positive.

Secondly, X-rays can show destructive damage, and some soft tissue issues.


Based on the cause. In allergy, avoid the allergen, and taking antihistamines. In inflammatory arthritis, start with NSAIDs, moving on all the way to immunosuppression.

Sometimes it may be necessary to undergo joint replacement, for example in severe hip or knee osteoarthritis.
