These small cushions are called ‘bursa’, and they reduce wear and tear on the tendon as it moves over the bone. Sometimes these cushions become inflamed and painful. Common sites for bursitis include the shoulder (subacromial bursa), hip (trochanteric bursa), knee (prepatellar bursa), elbow (olecranon bursa), Achilles tendon (retrocalcaneal bursa) and foot. The usual treatment is RICE – rest, ice, compression, elevation. Anti-inflammatory medicines may help. Your doctor or physiotherapist may also recommend specific stretches. You should see your doctor if pain and swelling persists despite treatment. Follow the links below to find trusted information about bursitis.
