In your heel, there is a sac filled with fluid known as a bursa. It is located under your Achilles tendon at the back of your heel bone. Many of your large joints have a bursa around them. They provide cushioning and lubrication for the tendons, muscles and bone. Bursitis of the heel occurs when the bursa in your ankle becomes swollen.
Bursitis can develop for several reasons, including repetitively engaging in the same motion, or example, lifting objects above your head for work. Putting a lot of pressure on a bursa for an extended period of time. Leaning on your elbows or kneeling (for example, to lay carpet) can cause bursitis in the elbows or knees. If you sit for long periods of time, especially on hard surfaces, you may develop bursitis in your hip. Wearing shoes with a stiff back that rubs against the back of the ankle can cause Achilles tendon bursitis. Trauma. The bursae at the knee and elbow are close to the surface of the skin, and if you fall directly on your elbow or the knee, you can rupture, injure or puncture a bursa. Infection. Known as septic bursitis, it?s the result of bacteria infecting a bursa. It can occur from an infection traveling from another site or following an accident that ruptures the bursa. Even scraping the skin on your elbow or getting a mosquito bite that breaks the skin near the olecranon bursa (near the elbow) can lead to bursitis. Other joint disorders, such as rheumatoid arthritis, osteoarthritis and gout, or health conditions.
Pain at the back of the heel at the attachment site of the Achilles tendon when running. Pain on palpation of the back of the heel or bottom of heel. Pain when standing on tiptoes. Swelling and redness at the back and bottom of the heel.
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
Rest and apply cold therapy or ice. Ice should not be applied directly to the skin as it may cause ice burns but wrap in a wet tea towel. Commercially available hot and cold packs are often more convenience than using ice. Taping the bursa with a donut shaped pad to take some of the pressure from footwear may help. A doctor may prescribe anti-inflammatory medication e.g. ibuprofen to reduce the pain and inflammation. Applying electrotherapy such as ultrasound may reduce inflammation and swelling. A steroid injection followed by 48 hours rest may be given for persistent cases. If the bursitis is particularly bad and does not respond to conservative treatment then surgery is also an option.
Surgery is rarely done strictly for treatment of a bursitis. If any underlying cause is the reason, this may be addressed surgically. During surgery for other conditions, a bursa may be seen and removed surgically.
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.
