A heel spur is an abnormal growth of the heel bone, the largest bone in the foot which absorbs the greatest amount of shock and pressure. Calcium deposits form when the plantar fascia pulls away from the heel area, causing a bony protrusion, or heel spur to develop. The plantar fascia is a broad band of fibrous tissue located along the bottom surface of the foot that runs from the heel to the forefoot. Heel spurs can cause extreme pain in the rearfoot, especially while standing or walking.
Generally caused by lack of flexibility in the calf muscles and/or excess weight, heel spurs occur when the foot bone is exposed to constant stress and calcium deposit build-up on the bottom of the heel bone. Repeated damage can cause these deposits to pile up on each other, presenting a spur-shaped deformity.
Heel spurs often do not show any symptoms. If you have intermittent or chronic pain when you walk, run or jog, it may be heel spur. There will be inflammation the point where spur formation happens. The pain is caused by soft tissue injury in the heel. Patients often describe the pain as a pin or knife sticking to the heel. The pain is more specially in the morning when the patient stands up for the first time.
A thorough history and physical exam is always necessary for the proper diagnosis of heel spurs and other foot conditions. X rays of the heel area are helpful, as excess bone production will be visible.
Non Surgical Treatment
Rest won?t help you in case of pain from the heel spur. When you get up after sleeping for some time, the pain may get worse. The pain worsens after a period of rest. You will feel pain because the plantar fascia elongates during working which stresses the heel. It is important to see a doctor if you are having consistent pain in you heel. The doctors may advise few or all of the conservative treatments, stretching exercises, shoe recommendations, shoe inserts or orthotic devices, physical therapy, taping or strapping to rest stressed muscles and tendons. There are some over-the-counter medicines available for treatment of heel pain. Acetaminophen (Tylenol), ibuprofen (Advil), or naproxen (Aleve) are some such medicines which can help you to get relief from the pain. In case of biomechanical imbalances causing the pain, a functional orthotic device can help you to get relief. Your doctor may also advise a corticosteroid injection for eliminating the inflammation.
Sometimes bone spurs can be surgically removed or an operation to loosen the fascia, called a plantar fascia release can be performed. This surgery is about 80 percent effective in the small group of individuals who do not have relief with conservative treatment, but symptoms may return if preventative measures (wearing proper footwear, shoe inserts, stretching, etc) are not maintained.
In 2002, researchers attempted to compare the effects of various running techniques on pronation and resulting injuries like stress fractures and heel spurs. They suggested that it is possible to teach runners to stride in such a way as to minimize impact forces. One way is to lower running speed. Another is to take longer rest periods following a run.
