What it is
It needs urgent treatment in hospital, usually with antibiotics into a vein and draining fluid from the joint.
Early treatment lowers the risk of lasting joint damage. Physiotherapy helps recovery.
Common signs
- Sudden, intense pain in a joint
- Swelling, redness and warmth over the joint
- Being unable to move the joint
- A high temperature
- A child limping or not using a limb
How it is usually diagnosed
- Taking fluid from the joint to test for bacteria
- Blood tests
- X-ray, ultrasound or MRI
Records worth keeping
Keeping these together makes each appointment easier, especially when you see a new doctor:
- Joint fluid and blood test results
- Scan reports
- Surgery or procedure notes
- Discharge letters and antibiotic plans
Questions to ask your doctor
- How long will I need antibiotics?
- Could the joint be damaged long term?
- What should I watch for after going home?
When to get help right away
Call 112 or go to the nearest emergency department if you have:
- A hot, swollen, very painful joint with a fever, or a child who suddenly will not walk or use a limb: get urgent help, call 112
