Bursitis

Joints in the human body contain small sacs of fluid which are intented to help structures slide over one another. But if jarred, these bursae can become inflamed and quite painful. Chronic bursitis of the knee is common among those who run on unyielding surfaces like roads and artificial turf. As a result of this stress, extra fluid can build up and accumulate in the bursae. Symptoms of bursitis include severe pain, especially in response to touch or movement, and limited range of motion. A health care professional usually diagnoses bursitis by palpating, examining the affected area, and taking a history of the injury.

Bursitis can require medical treatment; methods could include pressure bandages and diathermy, which uses high frequency electric current to apply heat beneath the skin. In some instances, the bursae might also be close enough to the skin surface to be penetrated with a needle to draw out the excess fluid. Surgery can also be used to treat bursitis. Acute bursitis which hurts not when the elbow or knee are moved but when touched, usually comes from impact on a hard surface. After the excess fluid has been removed, the condition can be treated with an ice-pack. Acute bursitis can be prevented by using protective gear, like knee and elbow pads.
