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.
Faulty foot structures such as abnormal growths, different leg lengths, and unhealed injuries and haveinf flat feet or high arches. Muscle imbalances tight, weak or shortened muscles in your foot, plantar fascia, ankle, calf and hamstring. Over pronation can cause imbalance in foot mechanics which puts excess pressure on the plantar fascia. Poor biomechanics affect the way your foot hits the ground. If you overpronate (feet roll inward) you tend to have flat feet (pes planus), which increases stress on the heel bone. Regular shoes or high heels that are too tight or don't support your heel or arch affect the distribution of your body weight on your foot. Health conditions such as obesity, inflammatory diseases (rheumatoid arthritis, ankylosing spondylitis), bursitis, neuroma (nerve growths), gout, diabetes, Haglund's deformity, and Achilles tendinitis can also instigate the problem. Running or jogging on hard surfaces, repetative striking of the heel bone.
Heel spurs result in a jabbing or aching sensation on or under the heel bone. The pain is often worst when you first arise in the morning and get to your feet. You may also experience pain when standing up after prolonged periods of sitting, such as work sessions at a desk or car rides. The discomfort may lessen after you spend several minutes walking, only to return later. Heel spurs can cause intermittent or chronic pain.
A Heel Spur diagnosis is made when an X-ray shows a hook of bone protruding from the bottom of the foot at the point where the plantar fascia is attached to the heel bone. The plantar fascia is the thick, connective tissue that runs from the calcaneus (heel bone) to the ball of the foot. This strong and tight tissue helps maintain the arch of the foot. It is also one of the major transmitters of weight across the foot as you walk or run. In other words, tremendous stress is placed on the plantar fascia.
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.
When chronic heel pain fails to respond to conservative treatment, surgical treatment may be necessary. Heel surgery can provide relief of pain and restore mobility. The type of procedure used is based on examination and usually consists of releasing the excessive tightness of the plantar fascia, called a plantar fascia release. Depending on the presence of excess bony build up, the procedure may or may not include removal of heel spurs. Similar to other surgical interventions, there are various modifications and surgical enhancements regarding surgery of the heel.
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.
