Bursitis is the inflammation or irritation of the bursa, a fluid-filled sac located between bone, muscle, tendons, and skin, that decreases rubbing, friction, and irritation. It is most often caused by repetitive, minor impact on the area, or from a sudden, more serious injury, and most often is found in elbows, shoulders, hips, knees, and the Achilles tendon. Bursitis, which is painful, is more common in people over 40. It is treated by avoiding aggravating activities, resting, icing the injury, and taking over-the-counter anti-inflammatory medicines.
