A bursa is a fluid-containing sac that is present at many areas of pressure on the body. Its job is to protect these areas of pressure by being a shock absorber. A bursitis is an abnormal inflammation of the bursa sac caused by abnormal excessive pressure, stress and/ or strain over the area it is protecting. On the heel bone, there are two bursa sacs: one on the bottom and the other on the back. Specifically on the bottom of the heel, it is known as an Inferior (bottom) Calcaneal (heel) Bursa. On the back of the heel, it is called the Retro (back) Calcaneal Bursa. When either of these bursas become abnormally stressed, strained, or swollen, the result is bursitis of the heel. It is this bursitis that is the reason for pain in the heel upon arising (Poststatic Dyskinesia) in the morning or after resting for a while. You can either develop these bursitises with or without the presence of heel spur (explanation to follow). As stated before, Morton?s Toe can cause this by causing over pronation in the foot.
Bursitis, tendinitis, and other soft tissue rheumatic syndromes typically result from one or more factors. These include: Play or work activities that cause overuse or injury to the joint areas Incorrect posture Stress on the soft tissues from an abnormal or poorly positioned joint or bone (such as leg length differences or arthritis in a joint) Other diseases or conditions (rheumatoid arthritis, gout, psoriasis, thyroid disease, or an unusual drug reaction) Infection.
In retrocalcaneal bursitis, pain at the back of the heel is the main complaint from patients. Pain may worsen when tip-toeing, running uphill, jumping or hopping. Often, those who are accustomed to wearing high-heeled shoes on a long-term basis may also complain of pain at the back of the heel when switching to flat shoes. This is because when in high-heeled shoes, the calf muscle and the Achilles tendon are in a shortened position. Switching to flat shoes would cause an increased stretch to the calf muscle and Achilles tendon, irritating the Achilles tendon and the retrocalcaneal bursa. Other symptoms may include redness and swelling at the back of the heel.
Your doctor will examine you, including an evaluation of your gait, while you are barefoot, your doctor will ask you to stand still and to walk in order to evaluate how your foot moves as you walk. An examination of your feet. Your doctor may compare your feet for any differences between them. Then your doctor may examine your painful foot for signs of tenderness, swelling, discoloration, muscle weakness and decreased range of motion. A neurological examination. The nerves and muscles may be evaluated by checking strength, sensation and reflexes. In addition to examining you, your health care professional may want to examine your shoes. Signs of excessive wear in certain parts of a shoe can provide valuable clues to problems in the way you walk and poor bone alignment. Depending on the results of your physical examination, you may need foot X-rays or other diagnostic tests.
Non Surgical Treatment
Despite appropriate physiotherapy management, some patients with retrocalcaneal bursitis do not improve adequately. When this occurs the treating physiotherapist or doctor can advise on the best course of management. This may include further investigations such as an ultrasound, X-Ray, MRI or CT scan, pharmaceutical intervention, corticosteroid and anaesthetic injection into the retrocalcaneal bursa, draining of the bursa, or review by a specialist or podiatrist who can advise on any treatment that may be appropriate to improve the condition.
Surgery is rarely need to treat most of these conditions. A patient with a soft tissue rheumatic syndrome may need surgery, however, if problems persist and other treatment methods do not help symptoms.
People can lower the risk of bursitis by gradually strengthening and stretching the muscles around the joints and taking regular breaks from repetitive motion that might irritate bursae. Prolonged time resting on the elbows or kneeling should be avoided, if it cannot be avoided, wearing cushioned elbow and knee pads can help protect the bursae. Comfortable, supportive, low-heeled shoes can help prevent bursitis in the foot.
