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.
A heel spur usually develops as a result of wear and tear over time, which leads to the degeneration of connective tissue called fascia. Standing for prolonged periods and wearing shoes that do not provide the right type of arch support can also lead to connective tissue damage in the heel. The body attempts to repair the damaged tissue by delivering calcium to the affected region, but sometimes too much calcium begins to accumulate and this results in painful plantar fasciitis.
You'll typically first notice early heel spur pain under your heel in the morning or after resting. Your heel pain will be worse with the first steps and improves with activity as it warms up. When you palpate the tender area you may feel a tender bony lump. As your plantar fasciitis deteriorates and your heel spur grows, the pain will be present more often.
Sharp pain localized to the heel may be all a doctor needs to understand in order to diagnose the presence of heel spurs. However, you may also be sent to a radiologist for X-rays to confirm the presence of heel spurs.
Non Surgical Treatment
Heel spurs can be treated by wearing orthotic insoles inside the shoe. Orthotics are designed to correct incorrect gait, in particular over-pronation (rolling in of the foot and collapsing of the arches). Over-pronation is a very common foot condition, affecting at least half of the population. It is a major contributing cause of heel spurs. Orthotics are very effective in that the device corrects the foot to its natural position. By supporting the arches properly and preventing excess rolling in of the foot, the plantar fascia is placed under much less strain and stress compared to an unsupported foot. Less strain on the ligament means less pulling away from the heel bone, allowing the inflammation to heal faster. In addition to orthotic treatment, most podiatrists and physiotherapists recommend a series of exercises to help make the ligaments in the feet and legs longer and more flexible. In turn this will help reduce strain on the plantar fascia.
Surgery is used a very small percentage of the time. It is usually considered after trying non-surgical treatments for at least a year. Plantar fascia release surgery is use to relax the plantar fascia. This surgery is commonly paired with tarsal tunnel release surgery. Surgery is successful for the majority of people.
To prevent this condition, wearing shoes with proper arches and support is very important. Proper stretching is always a necessity, especially when there is an increase in activities or a change in running technique. It is not recommended to attempt working through the pain, as this can change a mild case of heel spurs and plantar fascitis into a long lasting and painful episode of this condition.
