Reactive arthritis

Reactive arthritis is a relatively short-lived inflammatory arthritis which usually develops after an infection of the throat, bowel, or genital tract.

The main symptoms are joint pain, stiffness and swelling (usually in the lower limb joints such as knees or ankles) and is associated with swelling and tenderness of the tendons surrounding the joints and sausage-like swelling of fingers or toes (dactylitis).

It can also be associated with inflammation of the eyes (conjunctivitis), scaly rashes on hands or feet, diarrhoea (usually prior to the onset of joint symptoms), mouth ulcers, and inflammation of the genital tract (causing discharge from the penis or vagina).
