A bursa is a fluid-filled sac. There are hundreds of deep and superficial bursae throughout the human body. They are typically located near major joints. Bursae are situated between bone and soft tissues like tendons, ligaments, muscles, and skin. They serve as a cushioning pad to absorb shock. The fluid within the sac is secreted to assist with friction-free movement as the soft tissues move across a bony area.
Improper foot wear, tight shoes or shoes that do not fit properly can cause extra pressure and friction on the back of the heel. Overtime, this pressure causes irritation of the bursae that protects the Achilles tendon causing one or both to swell and become inflamed. Athletes who overtrain or runners that increase their distance to quickly are at greater risk of experiencing Achilles bursitis. With over use, the Achilles bursae and tendon can become irritated and inflamed leading to thickening of the bursae lining and wearing of the tendon. Fluid builds in the bursa when it becomes irritated causing swelling of the Achilles bursa and pain at the back of the heel.
Pain in the heel, especially with walking, running, or when the area is touched. Pain may get worse when rising on the toes (standing on tiptoes). Red, warm skin over the back of the heel.
To begin with, your doctor will gather a medical history about you and your current condition and symptoms. He/she will inquire about the level of your heel pain, the how long you have had the symptoms and the limitations you are experiencing. Details about what and when the pain started, all are very helpful in providing you with a diagnoses of your ankle / heel.
Non Surgical Treatment
Conservative treatment includes the use of shoe supports (either a heel raise or a donut-shaped heel cushion) and a limited number of local corticosteroid injections (usually up to three per year). Changing the type of footwear may be essential.
Bursectomy is a surgical procedure used to remove an inflamed or infected bursa, which is a fluid-filled sac that reduces friction between tissues of the body. Because retrocalcaneal bursitis can cause chronic inflammation, pain and discomfort, bursectomy may be used as a treatment for the condition when it is persistent and cannot be relived with other treatments. During this procedure, a surgeon makes small incisions so that a camera may be inserted into the joint. This camera is called an arthroscope. Another small incision is made so that surgical instruments can be inserted to remove the inflamed bursa.
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.
