Bursitis Of The Foot Physiology

Overview
A Bursa is a small fluid filled sac that forms in areas of extra rubbing and friction. They are usually present with a bone deformity as the bone is pressed against other structures like a tendon or against the ground as you walk. The bursa acts as a shock absorber and is a way for your body to protect you from damage. When this bursa or sac like structure becomes swollen and inflammed it is called bursitis. The bursa may be anatomical meaning normally present, or it may be adventitious meaning, only present because of a problem. Many bursa are present and do not cause pain.

Causes
Posterior heel pain can come from one of several causes. When a physician is talking about posterior heel pain, he or she is referring to pain behind the heel, not below it. Pain underneath the heel, on the bottom of the foot, has several causes including Tarsal Tunnel Syndrome. Plantar Fasciitis. Heel Spurs.

Symptoms
Pain at the back of the heel, especially with jumping, hopping, tip-toeing, walking or running uphill or on soft surfaces. If tendonitis is also present, the pain can radiate away from the bursa. Direct pressure on the bursa will exacerbate the pain and should be avoided if possible. Tenderness and swelling which might make it difficult to wear certain shoes on the feet. As the bursa becomes more inflamed you will experience swelling and warmth. In severe cases, the bursa will appear as a bump, called a "pump bump", and is usually red, and extremely tender. Swelling can cause difficulties moving as the range of motion in the ankle can be affected. Limping due to the pain may occur. If you press on both sides of the inflamed heel, there may be a firm spongy feeling. Weakness in the tendons and muscles surrounding the bursa can develop as the pain worsens and the inflammation in the area spreads. Possibly a fever if you are suffering from septic bursitis (You will need to see a doctor for medication to get rid of the infection). Pain at the back of the heel makes it difficult to continue wearing shoes, especially high heels with straps or shoes that don't fit properly.

Diagnosis
A physical examination will be performed to determine if you have any signs of Achilles Bursitis or other ankle injury. He/she will look and feel the soft tissue and bones in your ankles to note any differences between the two of them. This will identify any abnormalities, such as swelling, bone deformities, atrophied muscles, redness and/or warmth on the skin. In many cases, the first sign that you have Achilles bursitis is swelling in the back of the foot and ankle pain.

Non Surgical Treatment
The underlying cause of the bursitis must be identified to prevent further reoccurrences. Failure to eliminate the cause will lead to future flare ups and a poor and slow recovery. Future occurrences can be prevented with the use of stretches and strengthening exercises which will help prevent the muscles from tightening up over the bursa, Pilates and yoga are very good for this providing the aggravating movements are avoided. Wearing joint supports such as knee pads or elbow supports may also reduce the likelihood of redeveloping bursitis.

Prevention
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.
