A heel spur is caused by the displacement of calcium on the bone that forms on the underside of the heel, it may be one small bony protrusion or a collection of tiny, irregularly shaped growths on the bone of the heel, which is called the calcaneum. Heel spurs are sometimes painful, described as a knife digging into the heel and other times, a heel spur goes unnoticed and is only detected by an X-ray.
A major cause of heel spur pain comes from the development of new fibrous tissue around the bony spur, which acts as a cushion over the area of stress. As this tissue grows, a callus forms and takes up even more space than the heel spur, leading to less space for the thick surrounding network of tendons, nerves, ligaments and supporting tissue. These important structures in the foot have limited space because of calcium or tissue buildup, which leads to swelling and redness of the foot, and a deep throbbing pain worsened with exercise.
Heel spurs may or may not cause symptoms. Symptoms are usually related to the plantar fasciitis. You may experience significant pain. Your heel pain may be worse in the morning when you first wake up or during certain activities.
Diagnosis is made using a few different technologies. X-rays are often used first to ensure there is no fracture or tumor in the region. Then ultrasound is used to check the fascia itself to make sure there is no tear and check the level of scar tissue and damage. Neurosensory testing, a non-painful nerve test, can be used to make sure there is not a local nerve problem if the pain is thought to be nerve related. It is important to remember that one can have a very large heel spur and no plantar fasciitis issues or pain at all, or one can have a great deal of pain and virtually no spur at all.
Non Surgical Treatment
Heel spurs can be solved with simple solutions that do not involve surgery. Avoiding extended periods of activity such as running, sports and walking. Applying ice directly to the heel for 5 minutes at a time. This helps soothe and reduce inflammation. Lose weight to reduce stress on your heels. A series of simple exercises. Inexpensive orthotic shoe inserts. The best way to treat heel spurs is by treating the underlying cause of the problem. This involves correcting the dynamics of your foot motion with orthotic insoles.
Approximately 2% of people with painful heel spurs need surgery, meaning that 98 out of 100 people do well with the non-surgical treatments previously described. However, these treatments can sometimes be rather long and drawn out, and may become considerably expensive. Surgery should be considered when conservative treatment is unable to control and prevent the pain. If the pain goes away for a while, and continues to come back off and on, despite conservative treatments, surgery should be considered. If the pain really never goes away, but reaches a plateau, beyond which it does not improve despite conservative treatments, surgery should be considered. If the pain requires three or more injections of "cortisone" into the heel within a twelve month period, surgery should be considered.
Heel Spur symptoms can be prevented from returning by wearing proper shoes and using customized orthotics and insoles to relieve pressure. It is important to perform your exercises to help keep your foot stretched and relaxed.
