A bursa is a closed, fluid-filled sac that functions as a cushion and gliding surface to reduce friction between tissues of the body. The major bursae are located adjacent to the tendons near the
large joints, such as in the shoulders, elbows, hips, and knees. When the bursa becomes inflamed, the condition is known as bursitis. Bursitis is usually a temporary condition. It may restrain
motion, but generally does not cause deformity.
Bursitis occurs when the bursae become irritated or infected, often causing pain on movement. When infection is involved, medical intervention is necessary to fight the underlying infection and
prevent it from spreading, when infection is not involved, prompt medical attention can prevent the condition from becoming worse over time.
Your feet are extremely resilient and are designed to stand up to the pressures of day-to-day living. In some cases, though, foot structures may break down when subjected to chronic stress associated
with prolonged periods of weight-bearing activity on concrete, asphalt, or other hard surfaces (especially when your footwear does not allow for appropriate weight distribution). Foot problems,
including infracalcaneal bursitis, are often exacerbated by poorly designed footwear, and pressure, impact, and shear forces can damage your feet over time. Bursal sacs are intended to minimize this
damage, but sometimes the bursa itself becomes inflamed.
In addition to a complete medical history and physical examination, diagnostic procedures for bursitis may include the following. X-ray. A diagnostic test that uses invisible electromagnetic energy
beams to produce images of internal tissues, bones, and organs onto film. Magnetic resonance imaging (MRI). A diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a
computer to produce detailed images of organs and structures within the body. Ultrasound. A diagnostic technique that uses high-frequency sound waves to create an image of the internal organs.
Aspiration. A procedure that involves removal of fluid from the swollen bursa to exclude infection or gout as causes of bursitis. Blood tests. Lab tests that are done to confirm or eliminate other

When retrocalcaneal bursitis is associated with tendonitis, it may be necessary to immobilize the ankle for several weeks to allow the Achilles tendon to heal. This can be done by placing a cast on
the ankle, which limits movement and allows the tendon to rest. Walking boots may also be used to limit ankle movement and allow people with retrocalcaneal bursitis to avoid putting pressure on the
To prevent bursitis of the heel in the first place, always keep proper form during exercise. In addition, don?t jump into exercises that are too intense without building up to them. Strengthen and
flex your ankle.
