Bursitis means inflammation of a bursa, a sac that lines many joints and allows tendons and muscles to move easily when the joint is moving. In the heel, bursitis may cause pain at the underside or back of the heel. In some cases, heel bursitis is related to structural problems of the foot that cause an abnormal gait (way of walking). In other cases, wearing shoes with poorly cushioned heels can trigger bursitis.
The most common cause of bursitis is repeated physical activity, but it can flare up for no known reason. It can also be caused by trauma, rheumatoid arthritis, gout, and acute or chronic infection.
Symptoms of bursitis usually occur after rest and relaxation. Upon activity there is usually more intense pain in the area of the bursa. The common areas to have a bursitis in the foot are in the bottom of the heel, behind the heel near the attachment of the Achilles Tendon as well as along the side of a bunion. A bursa may also form in multiple areas especially along the metatarsal heads, or "ball" of your foot. You may actually feel the sac like fluid when rubbing the area of pain.
Your GP or therapist will be able to diagnose you by both listening to your history and examining you. No X-rays or further investigation should be needed to confirm diagnosis but may be requested to check for any underlying health conditions that may have triggered the bursitis.
Non Surgical Treatment
Relieving the symptoms of bursitis initially focuses on taking the pressure off the bursa. This can be done with proper cushioning, inserts, or footwear but may require surgery if it is a bone formation problem (i.e. Huglund's Deformity). If your bursitis is caused by an infection (septic bursitis), the doctor will probably drain the bursa sac with a needle and prescribe antibiotics to treat the infection.
Surgery is rarely done strictly for treatment of a bursitis. If any underlying cause is the reason, this may be addressed surgically. During surgery for other conditions, a bursa may be seen and removed surgically.
Contact your physician if bursitis pain is disabling (when movement of the joint is largely or entirely restricted), if the pain doesn?t subside after a week of self-care, or if the joint is red and swollen. Also call your doctor if you develop a fever, which could signal infectious bursitis-a condition that especially can afflict the elbow. Except for the fever, symptoms resemble other forms of bursitis, but infectious bursitis requires immediate medical attention.
