Bone spurs (retrocalcaneal spur, or exostosis) can develop not only on the back of the heel, but also on the toes, mainly around the fifth (small) toe. Most often, they occur next to the toenail on the outside of the toe; on the inside of the toe near the tip, where the fifth toe presses against the fourth toe; and on the inside of the base of the toe. Bone spurs can also occur on the sides of the toes. This is usually due to wearing shoes that are too tight in the toe box, which causes the toes to press against each other. Bone spurs may also develop in the arch area of the top of the foot; this area becomes painful when you tie your shoelaces tightly or exert other pressure on that part of the foot. Formation of spurs in this area is often associated with arthritis.
Heel spurs develop as an abnormal growth in the heel bone due to calcium deposits that form when the plantar fascia pulls away from the heel. This stretching of the plantar fascia is usually the result of over-pronation (flat feet), but people with unusually high arches (pes cavus) can also develop heel spurs. Women have a significantly higher incidence of heel spurs due to the types of footwear often worn on a regular basis.
The spur itself is not painful, however, if it is sharp and pointed it can poke into soft tissue surrounding the spur itself. As the bone spur irritates the tissue, inflammation and bruising can occur leading to heel pain. Heel spurs can affect your ability to do your usual work and/or activities, and can also trap and irritate the nerves in your heel area. They can change the way you walk, and can lead to knee, hip and low back injuries. If severe, they may require medical intervention.
Your doctor will discuss your medical history and will examine your foot and heel for any deformities and inflammation (swelling, redness, heat, pain). He/she will analyze your flexibility, stability, and gait (the way you walk). Occasionally an x-ray or blood tests (to rule out diseases or infections) may be requested.
Non Surgical Treatment
The heel pain associated with heel spurs and plantar fasciitis may not respond well to rest. If you walk after a night's sleep, the pain may feel worse as the plantar fascia suddenly elongates, which stretches and pulls on the heel. The pain often decreases the more you walk. But you may feel a recurrence of pain after either prolonged rest or extensive walking. If you have heel pain that persists for more than one month, consult a health care provider. He or she may recommend conservative treatments such as stretching exercises, shoe recommendations, taping or strapping to rest stressed muscles and tendons, shoe inserts or orthotic devices, physical therapy. Heel pain may respond to treatment with over-the-counter medications such as acetaminophen (Tylenol), ibuprofen (Advil), or naproxen (Aleve). In many cases, a functional orthotic device can correct the causes of heel and arch pain such as biomechanical imbalances. In some cases, injection with a corticosteroid may be done to relieve inflammation in the area.
Have surgery if no other treatments work. Before performing surgery, doctors usually give home treatments and improved footwear about a year to work. When nothing else eases the pain, here's what you need to know about surgical options. Instep plantar fasciotomy. Doctors remove part of the plantar fascia to ease pressure on the nerves in your foot. Endoscopy. This surgery performs the same function as an instep plantar fasciotomy but uses smaller incisions so that you'll heal faster. However, endoscopy has a higher rate of nerve damage, so consider this before you opt for this option. Be prepared to wear a below-the-knee walking cast to ease the pain of surgery and to speed the healing process. These casts, or "boots," usually work better than crutches to speed up your recovery time.
A variety of steps can be taken to avoid heel pain and accompanying afflictions. Wear shoes that fit well-front, back, and sides-and have shock-absorbent soles, rigid shanks, and supportive heel counters. Wear the proper shoes for each activity. Do not wear shoes with excessive wear on heels or soles. Prepare properly before exercising. Warm up and do stretching exercises before and after running. Pace yourself when you participate in athletic activities. Don't underestimate your body's need for rest and good nutrition. If obese, lose weight.
