A bursa is a fluid filled sack which lies between two structures and is designed to reduce friction between those structures. There are two types of bursa, those that occur in everybody and those that form due to trauma.
Occasionally a bursa may become irritated causing it to swell up and hurt.
This is called bursitis. It often occurs in the ball of the foot, around the back of the heel, the front and sides of the knee, and the hip.
To treat a bursitis first the cause of the irritation must be removed. This may be done using modifications to footware, changes in activity, or orthotics. Occasionally a cortisone injection can provide rapid pain relief while other interventions take effect. All of these treatments can be provided in house at Forest Lake Podiatry Clinic.
