Heel pain is often the result of a heel spur, which is a bone growth on the heel bone. Heel spurs are usually located on the underside of the heel bone where it attaches to the plantar fascia, a long band of connective tissue running from the heel to the ball of the foot. This connective tissue holds the arch together and acts as a shock absorber during activity. If the plantar fascia is over-stretched from running, wearing poor-fitting shoes or being overweight, pain can result from the stress and inflammation of the tissue pulling on the bone. Over time, the body builds extra bone in response to this stress resulting in heel spurs.
Long standing inflammation causes the deposition of calcium at the point where the plantar fascia inserts into the heel. This results in the appearance of a sharp thorn like heel spur on x-ray. The heel spur is asymptomatic (not painful), the pain arises from the inflammation of the plantar fascia.
Pain in the heel can be caused by many things. The commonest cause is plantar fascitis. Other causes include, being overweight, constantly being on your feet, especially on a hard surface like concrete and wearing hard-soled footwear, thinning or weakness of the fat pads of the heel, injury to the bones or padding of the heel, arthritis in the ankle or heel (subtalar) joint, irritation of the nerves on the inner or outer sides of the heel, fracture of the heel bone (calcaneum).
The diagnosis of heel pain and heel spurs is made by a through history of the course of the condition and by physical exam. Weight bearing x-rays are useful in determining if a heel spur is present and to rule out rare causes of heel pain such as a stress fracture of the heel bone, the presence of bone tumors or evidence of soft tissue damage caused by certain connective tissue disorders.
Non Surgical Treatment
If you still have pain after several weeks, see your foot and ankle surgeon, who may add one or more of these treatment approaches, padding and strapping. Placing pads in the shoe softens the impact of walking. Strapping helps support the foot and reduce strain on the fascia. Orthotic devices. Custom orthotic devices that fit into your shoe help correct the underlying structural abnormalities causing the plantar fasciitis. Injection therapy. In some cases, corticosteroid injections are used to help reduce the inflammation and relieve pain. Removable walking cast. A removable walking cast may be used to keep your foot immobile for a few weeks to allow it to rest and heal. Night splint. Wearing a night splint allows you to maintain an extended stretch of the plantar fascia while sleeping. This may help reduce the morning pain experienced by some patients. Physical therapy. Exercises and other physical therapy measures may be used to help provide relief.
It is rare to need an operation for heel pain. It would only be offered if all simpler treatments have failed and, in particular, you are a reasonable weight for your height and the stresses on your heel cannot be improved by modifying your activities or footwear. The aim of an operation is to release part of the plantar fascia from the heel bone and reduce the tension in it. Many surgeons would also explore and free the small nerves on the inner side of your heel as these are sometimes trapped by bands of tight tissue. This sort of surgery can be done through a cut about 3cm long on the inner side of your heel. Recently there has been a lot of interest in doing the operation by keyhole surgery, but this has not yet been proven to be effective and safe. Most people who have an operation are better afterwards, but it can take months to get the benefit of the operation and the wound can take a while to heal fully. Tingling or numbness on the side of the heel may occur after operation.

Being overweight can place excess pressure and strain on your feet, particularly on your heels. Losing weight, and maintaining a healthy weight by combining regular exercise with a healthy, balanced diet, can be beneficial for your feet. Wearing appropriate footwear is also important. Ideally, you should wear shoes with a low to moderate heel that supports and cushions your arches and heels. Avoid wearing shoes with no heels.
