Bone spurs including heel spurs occur as a natural response of the body to wear and tear. Heel spur in particular, can cause pain when it rubs against soft tissues including the Achilles tendon. When that happens movement can become restricted. Spurs can also appear in other joint areas such as under the toenail where it would lead to pain and nail deformation.
At the onset of this condition, pain and swelling become present, with discomfort particularly noted as pushing off with the toes occurs during walking. This movement of the foot stretches the fascia that is already irritated and inflamed. If this condition is allowed to continue, pain is noticed around the heel region because of the newly formed bone, in response to the stress. This results in the development of the heel spur. It is common among athletes and others who run and jump a significant amount.
The pain caused by a calcaneal spur is not the result of the pressure of weight on the point of the spur, but results from inflammation around the tendons where they attach to the heel bone. You might expect the pain to increase as you walk on the spur, but actually it decreases. The pain is most severe when you start to walk after a rest. The nerves and capillaries adapt themselves to the situation as you walk. When you rest, the nerves and capillaries rest, also. Then, as you begin to move about again, extreme demands are made on the blood vessels and nerves, which will cause pain until they again adjust to the spur. If excessive strain has been placed on the foot the day before, the pain may also be greater. A sudden strain, as might be produced by leaping or jumping, can also increase the pain. The pain might be localized at first, but continued walking and standing will soon cause the entire heel to become tender and painful.
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
Bone spurs rarely require treatment unless they are causing frequent pain or damaging other tissues. Because heel spurs and plantar fasciitis are so closely related, they are usually treated the same way. Symptomatic treatment involves rest, especially from the activity that is contributing to the condition and making symptoms worse (although this may not be easy to discover, as problems can manifest several hours or days after the harmful activity has occurred). If you identify the offending activity, ice is recommended immediately following it. Stretching of the calf muscles after a short warm up is also a good idea and can be helpful. Stretching exercises that gently lengthen the calm muscle will relax the tissue surrounding the heel and should be done several times a day, especially in the morning and after prolonged sitting.
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.
