Whenever tissues rub against one another, a bursa forms to allow for smooth gliding. A bursa is a fluid-filled sac and occurs normally throughout the body. Only a few cell layers thick, a bursa is filled with a lubricating fluid. However, when irritated, a bursa can become markedly thickened and painful. This is often referred to as bursitis. The retrocalcaneal bursa is positioned to allow the Achilles tendon to glide over the back part (posterior aspect) of the heel bone. When this bone becomes enlarged, inflammation of the retrocalcaneal bursa occurs. This inflammation results in exquisite tenderness along the posterior aspect of the heel.
Bursitis of the Achilles tendon is caused by the irritation and inflammation of the retrocalcaneal bursa, a small fluid-filled sac located in the back of the ankle that acts as a cushion and lubricant for the ankle joint. Possible causes of Achilles tendon bursitis include aging, Factors related to the aging process, including the onset of rheumatoid arthritis and gout, can deteriorate the bursa. Overuse of ankle. Excessive walking, uphill running, jumping, and other aggressive exercise regimens, especially without proper conditioning, can cause irritation to the bursa. Trauma. Sudden injury to the ankle joint, or trauma caused by rigid or improperly fitted shoes, can increase the chances of developing bursitis.
Pain or tenderness at the back of the heel around the Achilles region. Increased pain during activities with strong, repetitive calf contractions, walking (uphill), stair climbing, running, jumping. Pain may be worse with rest after activity (that night or the next morning) or at the beginning of the excercise. Pain when wearing shoes and the heel is getting rubbed. Bump forming on the back of the heel. Limping. Stiffness. Decreased range of motion. Redness and warmth (if the bursa gets infected).
Medical examination is not necessarily required in light cases where the tenderness is minimal. In all cases where smooth improvement is not experienced, medical attention should be sought as soon as possible to exclude a (partial) rupture of the Achilles tendon or rupture of the soleus muscle. This situation is best determined by use of ultrasound scanning, as a number of injuries requiring treatment can easily be overlooked during a clinical examination (Ultrasonic image). Ultrasound scanning enables an evaluation of the extent of the change in the tendon, inflammation of the tendon (tendinitis), development of cicatricial tissue (tendinosis), calcification, inflammation of the tissue surrounding the tendon (peritendinitis), inflammation of the bursa (bursitis), as well as (partial) rupture.
Non Surgical Treatment
You should rest from all activities that cause pain or limping. Use crutches/cane until you can walk without pain or limping. Ice. Place a plastic bag with ice on the foot for 15-20 minutes, 3-5 times a day for the first 24-72 hours. Leave the ice off at least 1 1/2 hours between applications. Compression. Lightly wrap an elastic bandage from the toes to mid calf, using even pressure. Wear this until swelling decreases. Loosen the wrap if your toes start to turn blue or feel cold. Elevate. Make sure to elevate the ankle above heart level. To improve symptoms of plantar calcaneal bursitis after the acute phasetry the baked bean tin stretch, using a baked bean tin roll the foot backwards and forwards. 2 minutes in the morning before putting the foot to the floor. 5-10 minutes every evening. Contrast foot baths. 10 minutes warm water. 10 minutes cool water morning and evening (morning may be missed if time is restricted). Stretches. Start with 10 stretches per day, holding the stretch for 30 seconds, then relax and then repeat. Continue this stretch daily until you can no longer feel it pulling on the heel, then progress to stretch. Do 10 per day holding for 30 seconds per stretch. When you can no longer feel it pulling on the heel proceed to stretches. Do 10 per day holding for 30 seconds on every stretch.
Surgery to remove the damaged bursa may be performed in extreme cases. If the bursitis is caused by an infection, then additional treatment is needed. Septic bursitis is caused by the presence of a pus-forming organism, usually staphylococcus aureus. This is confirmed by examining a sample of the fluid in the bursa and requires treatment with antibiotics taken by mouth, injected into a muscle or into a vein (intravenously). The bursa will also need to be drained by needle two or three times over the first week of treatment. When a patient has such a serious infection, there may be underlying causes. There could be undiscovered diabetes, or an inefficient immune system caused by human immunodeficiency virus infection (HIV).
