Bursitis is an inflammation of a small fluid-filled sac, called a bursa, located near a joint, bone or tendon. The bursa, which protects the area from friction, can become inflamed from repetitive motion or irritation from shoes. In the foot, the heel and the toes are most often affected. Symptoms of bursitis include localized redness, swelling and pain. Treatment may include resting the affected area, local ice therapy, nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, padding or corticosteroid injections to help reduce inflammation and relieve pain. If these nonsurgical treatments fail to provide adequate pain relief, surgery may be needed.
