A common cause of heel pain is the heel spur, a bony growth on the underside of the heel bone. The spur, visible by X-ray, appears as a protrusion that can extend forward as much as half an inch. When there is no indication of bone enlargement, the condition is sometimes referred to as "heel spur syndrome." Heel spurs result from strain on the muscles and ligaments of the foot, by stretching of the long band of tissue that connects the heel and the ball of the foot, and by repeated tearing away of the lining or membrane that covers the heel bone. These conditions may result from biomechanical imbalance, running or jogging, improperly fitted or excessively worn shoes, or obesity.
These bony protrusions are commonly found in association with a condition called Plantar Fasciitis. Plantar Fasciitis occurs when the plantar fascia ligament, which spans the arch of the foot, becomes stressed, torn and inflamed. Misalignment and excessive movement of the plantar fascia ligament is most typically the result of an abnormal walking gait. The ligament is designed to stretch with the bounce of each step you take, but if it stretches too much, the resulting small tears and inflammation can cause mild to extreme discomfort. At the same time, it is believed that heel spurs are formed as the body attempts to provide some additional support to the over-stretched ligament. In other words, calcium builds up as a prop to the plantar fascia.
Although it may take years to become a problem, once it appears, it may cause considerable suffering. Because of proximity to the tendons, the spur is a source of continuous painful aching. The sensation has been described as "a toothache in the foot." When you place your weight on the heel, the pain can be sufficient to immobilize you.
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
Perform some exercises. Exercises that strengthen and lengthen your plantar fascia can also be very helpful for heel spurs. Try some of the following activities. Calf stretch. Place your hands on a wall. Extend 1 foot (0.3 m) behind you with your knee straight and place the other foot in front of you with the knee bent. Push your hips toward the wall and hold the stretch for 10 seconds. You should feel a pull in your calf muscles. Repeat the stretch 20 times for each foot. Plantar fascia stretch, Perform this exercise in the morning before you've done any standing or walking. Cross your injured foot over the knee of your other leg. Grasp your toes and gently pull them toward you. If you can't reach your toes, then wrap a towel around them and pull on the towel. Hold the stretch for 10 seconds and repeat 20 times for each foot.
Usually, heel spurs are curable with conservative treatment. If not, heel spurs are curable with surgery, although there is the possibility of them growing back. About 10% of those who continue to see a physician for plantar fascitis have it for more than a year. If there is limited success after approximately one year of conservative treatment, patients are often advised to have surgery.
Choose new shoes that are the right size. Have your foot measured when you go to the shoe store instead of taking a guess about the size. Also, try on shoes at the end of the day or after a workout, when your feet are at their largest. To ensure a good fit, wear the same type of socks or nylons that you would normally wear with the type of shoe that you are trying on.
