When walking, your heels repeatedly hit the ground with considerable force. They have to be able to absorb the impact and provide a firm support for the weight of the body. When pain develops in the heel, it can be very disabling, making every step a problem, affecting your posture. There are various types of heel pain. Some of the most common are: heel spurs (plantar fasciitis); heel bursitis and heel bumps.
To understand the cause of the pain one must understand the anatomy of the foot and some basic mechanics in the function of the foot. A thick ligament, called the plantar fascia, is attached into the bottom of the heel and fans out into the ball of the foot, attaching into the base of the toes. The plantar fascia is made of dense, fibrous connective tissue that will stretch very little. It acts something like a shock absorber. As the foot impacts the ground with each step, it flattens out lengthening the foot. This action pulls on the plantar fascia, which stretches slightly. When the heel comes off the ground the tension on the ligament is released. Anything that causes the foot to flatten excessively will cause the plantar fascia to stretch greater that it is accustom to doing. One consequence of this is the development of small tears where the ligament attaches into the heel bone. When these small tears occur, a very small amount of bleeding occurs and the tension of the plantar fascia on the heel bone produces a spur on the bottom of the heel to form. Pain experienced in the bottom of the heel is not produced by the presence of the spur. The pain is due to excessive tension of the plantar fascia as it tears from its attachment into the heel bone. Heel spur formation is secondary to the excessive pull of the plantar fascia where it attaches to the heel bone. Many people have heel spurs at the attachment of the plantar fascia with out having any symptoms or pain. There are some less common causes of heel pain but they are relatively uncommon. There are several factors that cause the foot to flatten and excessively stretching the plantar fascia. The primary factor is the structure of a joint complex below the ankle joint, called the subtalar joint. The movement of this joint complex causes the arch of the foot to flatten and to heighten. Flattening of the arch of the foot is termed pronation and heightening of the arch is called supination. If there is excessive pronation of the foot during walking and standing, the plantar fascia is strained. Over time, this will cause a weakening of the ligament where it attaches into the heel bone, causing pain. When a person is at rest and off of their feet, the plantar fascia attempts to mend itself. Then, with the first few steps the fascia re-tears causing pain. Generally, after the first few steps the pain diminishes. This is why the heel pain tends to be worse the first few steps in the morning or after rest. Another factor that contributes to the flattening of the arch of the foot is tightness of the calf muscles. The calf muscle attaches into the foot by the achilles tendon into the back of the heel. When the calf muscle is tight it limits the movement of the ankle joint. When ankle joint motion is limited by the tightness of the calf muscle it forces the subtalar joint to pronate excessively. Excessive subtalar joint pronation can cause several different problems to occur in the foot. In this instance, it results in excessive tension of the plantar fascia. Tightness of the calf muscles can be a result of several different factors. Exercise, such as walking or jogging will cause the calf muscle to tighten. Inactivity or prolonged rest will also cause the calf muscle to tighten. Women who wear high heels and men who wear western style cowboy boots will, over time, develop tightness in the calf muscles.
Plantar fascia usually causes pain and stiffness on the bottom of your heel although some people have heel spurs and suffer no symptoms at all. Occasionally, heel pain is also associated with other medical disorders such as arthritis (inflammation of the joint), bursitis (inflammation of the tissues around the joint). Those who have symptoms may experience ?First step? pain (stone bruise sensation) after getting out of bed or sitting for a period of time. Pain after driving. Pain on the bottom of your heel. Deep aching pain. Pain can be worse when barefoot.
Your doctor will listen to your complaints about your heel and examine you to see what is causing the pain, and whether anything else has started it off. If the cause of your pain seems obvious, your doctor may be happy to start treatment straight away. However, some tests may be helpful in ruling out other problems. Blood tests may be done for arthritis. An Xray will show any arthritis in the ankle or subtalar joint, as well as any fracture or cyst in the calcaneum. (It will also show a spur if you have one, but as we know this is not the cause of the pain.) Occasionally a scan may be used to help spot arthritis or a stress fracture.
Non Surgical Treatment
Shoes, orthoses, splinting and/or immobilization form the cornerstone for successful functional management of plantar fasciitis.When you take the overuse nature of plantar fasciitis into account and attempt to re-establish the windlass mechanism of the foot, there is an enhanced potential for success. Unfortunately, too little attention has been directed to appropriately managing the shoes worn during treatment for plantar fasciitis. Emphasising motion control and stability type athletic shoes (that provide a firm heel cup, instep rigidity, longitudinal integrity and a well-integrated shoe upper) can help decrease excess eccentric tissue strain. The shoe also serves as a vital and functional link between an orthotic and the foot. Orthoses have long been considered to be a reliable method for treating plantar fasciitis. Considerable debate has been waged over the benefits of over-the-counter (OTC), prefabricated and prescription foot and/or ankle orthoses. Heel cushions, heel cups and cushioning pads appear to provide immediate pain relief for many people who have plantar fasciitis.This relief is frequently short-lived and requires other treatment modalities for success.Neutral position taping and strapping of the foot provides temporary symptomatic relief of pain caused by plantar fasciitis. Although the functional benefits are temporary and likely do not last longer than 10 minutes with exercise, the soft tissue compression and symptomatic relief afforded by the strapping can last for nearly a week.
Surgery to correct heel pain is generally only recommended if orthotic treatment has failed. There are some exceptions to this course of treatment and it is up to you and your doctor to determine the most appropriate course of treatment. Following surgical treatment to correct heel pain the patient will generally have to continue the use of orthotics. The surgery does not correct the cause of the heel pain. The surgery will eliminate the pain but the process that caused the pain will continue without the use of orthotics. If orthotics have been prescribed prior to surgery they generally do not have to be remade.

You can reduce the risk of heel pain in many ways, including. Wear shoes that fit you properly with a firm fastening, such as laces. Choose shoes with shock-absorbent soles and supportive heels. Repair or throw out any shoes that have worn heels. Always warm up and cool down when exercising or playing sport, include plenty of slow, sustained stretches. If necessary, your podiatrist will show you how to tape or strap your feet to help support the muscles and ligaments. Shoe inserts (orthoses) professionally fitted by your podiatrist can help support your feet in the long term.
