Reactive arthritis is an inflammatory reaction in joints that usually develops one to several weeks after an infection of the bowel, urinary tract or genitals. The bacterium is usually not in the joint, but a warm, swollen joint with fever must first be assessed for an actual joint infection.

  • Pain, swelling, warmth and stiffness in one or a few joints, often a knee, ankle, toe or foot.
  • Pain at the heel or another tendon attachment site, sometimes with swelling of an entire finger or toe.
  • Keep moving within your pain limits and avoid prolonged complete rest; alternate activity with recovery.
  • Briefly cool a warm, swollen joint with a cloth between the skin and cold source, and do not force the joint.
  • Call the same day for a newly warm, red and swollen joint, especially with fever or feeling ill.
  • For urgent GP care outside normal opening hours, call HAP 9252. Call Ambulance 912 only for an immediately life-threatening situation.

A suddenly red, hot, swollen and very painful joint, especially with fever or feeling unwell, needs urgent assessment the same day.
