There are approximately 75 different causes of heel pain. At least 80% of all heel pain is due to heel spurs. A heel spur contains calcium, but cannot truly be called a calcium deposit. Bone spurs, whether they are on the heel or on any other bone of the body, are true bone -- they are true enlargements of the bone and may be sharp and pointed, or round and knobby. Since bone spurs are true bone, they contain calcium just like regular bones, but are not pure calcium deposits.
There exists a membrane that covers most of the bone along the heel. When this membrane gets torn repeatedly due to straining of the muscles in the foot, the calcium deposits that lead to heel spurs are more likely to occur.
The Heel Spur itself is not thought to be painful. Patients who experience pain with Plantar Fasciitis are suffering from inflammation and irritation of the plantar fascia. This the primary cause of pain and not the Heel Spur. Heel Spurs form in some patients who have plantar fasciitis, and tend to occur in patients who have had the problem for a prolonged period of time. While about 70 % of patients with plantar fasciitis have a heel spur, X-rays also show about 50 % of patients with no symptoms of plantar fasciitis also have a heel spur.
Diagnosis of a heel spur can be done with an x-ray, which will be able to reveal the bony spur. Normally, it occurs where the plantar fascia connects to the heel bone. When the plantar fascia ligament is pulled excessively it begins to pull away from the heel bone. When this excessive pulling occurs, it causes the body to respond by depositing calcium in the injured area, resulting in the formation of the bone spur. The Plantar fascia ligament is a fibrous band of connective tissue running between the heel bone and the ball of the foot. This structure maintains the arch of the foot and distributes weight along the foot as we walk. However, due to the stress that this ligament must endure, it can easily become damaged which commonly occurs along with heel spurs.
Non Surgical Treatment
In case of heel spurs rest is most important. Active sports, running, long walks etc should be avoided to start with. If you?re in a job that requires a lot of standing, take a few days off work. Rest (or reduced activity) is essential to allow the inflammation from becoming aggrevated. Furthermore, you can use ice packs (placed on the heel for 5-10 minutes) to ?cool down? the inflamed area. You may take anti-inflammatory medication or apply a topical inflammatory (i.e. a cream) to help reduce inflammation. In addition, there are some simple exercises that should be done daily to help relieve heel spur pain.
In a small number of cases (usually less than 5 percent), patients may not experience relief after trying the recommendations listed above. It is important that conservative treatments (such as those listed above) be performed for AT LEAST a year before considering surgery. Time is important in curing the pain from heel spurs, and insufficient treatment before surgery may subject you to potential complications from the procedure. If these treatments fail, your doctor may consider an operation to loosen the plantar fascia, called a plantar fascia release.
