This is a very common condition that leads to foot pain . Once you understand what it actually is you will wonder why it does not occur more often, particularly in the foot. It is an inflamed bursal sac. A bursal sac is a sac filled with fluid that acts to lubricate and reduce the friction between two surfaces in the body, usually muscles and tendons as they glide over bony prominences, however their purpose in not limited to just muscles and tendons. The body contains literally hundreds of bursal sacs but in the foot there is just one naturally occurring (adventitious) bursal sac. It is located between the Achilles tendon and the heel bone (calcaneaus), otherwise known as an achilles tendon bursal sac.In this instance the Achilles tendon is protected from the pressure of the heel bone pressing against it when we walk.
Wearing poorly fitting or constrictive footwear can cause the heel to become irritated and inflamed. Shoes that dig into the back of the heel are the primary cause of retroachilles bursitis. Foot or ankle deformity. A foot or ankle deformity can make it more likely to develop retrocalcaneal bursitis. For example, some people can have an abnormal, prominent shape of the top of their heel, known as a Haglund’s deformity. This condition increases the chances of irritating the bursa. A trauma to the affected heel, such as inadvertently striking the back of the heel against a hard object, can cause the bursa to fill with fluid, which in turn can irritate and inflame the bursa’s synovial membrane. Even though the body usually reabsorbs the fluid, the membrane may stay inflamed, causing bursitis symptoms.
Bursitis usually causes a dull pain, tenderness, and stiffness near the affected bursa. The bursa may swell and make the skin around it red and warm to the touch. Bursitis is most common in the shoulder camera.gif, elbow camera.gif, hip camera.gif, and knee camera.gif. Bursitis may also occur near the Achilles tendon or in the foot. Symptoms of bursitis may be like those of tendinopathy. Both occur in the tissues in and around the joints. Check with your doctor if your pain is severe, if the sore area becomes very hot or red, or if you have a fever.
Carrying out a diagnosis for bursitis is fairly straightforward. The doctor will examine the affected area and ask the patient some questions about his/her recent activities. If the patient has a high temperature the physician may take a small sample of fluid from a bursa near the affected body part. The sample will be tested for bacteria, and perhaps also crystals. If the patient does not get better after treatment the doctor may carry out further tests so that he/she can eliminate the possibility that the symptoms might not be due to something else. These may include an x-ray, to make sure no bones are broken or fractured. Blood tests, to check for rheumatoid arthritis. A CT scan or MRI scan to see if there is a torn tendon.
Non Surgical Treatment
Medications may be used to reduce the inflammation and pain of retrocalcaneal bursitis. Nonsteroidal anti-inflammatory drugs such as ibuprofen, naproxen and ketoprofen can be purchased without a prescription and used to treat mild to moderate pain. These drugs are often used in combination with a physical therapy program or other retrocalcaneal bursitis treatments.
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).
Because many soft tissue conditions are caused by overuse, the best treatment is prevention. It is important to avoid or modify the activities that cause problems. Underlying conditions such as leg length differences, improper position or poor technique in sports or work must be corrected. Be aware of potential overuse or injury in your daily activities and change your lifestyle to prevent problems. Otherwise, problems may persist or occur repeatedly. Following are some ways you can avoid future problems. Wear walking or jogging shoes that provide good support. High-top shoes provide support for people with ankle problems. Wear comfortable shoes that fit properly. Wear heel cups or other shoe inserts as recommended by your doctor. Exercise on level, graded surfaces.
