Plantar Fasciitis (Heel Pain)

Causes
Plantar fasciitis can come from a number of underlying causes. Finding the precise reason for the heel pain is sometimes difficult.

As you can imagine, when the foot is on the ground a tremendous amount of force (the full weight of the body) is concentrated on the plantar fascia. This force stretches the plantar fascia as the arch of the foot tries to flatten from the weight of your body. This is just how the string on a bow is stretched by the force of the bow trying to straighten. This leads to stress on the plantar fascia where it attaches to the heel bone. Small tears of the fascia can result. These tears are normally repaired by the body.

As this process of injury and repair repeats itself over and over again, bone spur (a pointed outgrowth of the bone) sometimes forms as the body’s response to try to firmly attach the fascia to the heelbone. This appears on an X-ray of the foot as a heel spur. Bone spurs occur along with plantar fasciitis but they are not the cause of the problem.

As we age, the very important fat pad that makes up the fleshy portion of the heel becomes thinner and degenerates (starts to break down). This can lead to inadequate padding on the heel. With less of a protective pad on the heel, there is a reduced amount of shock absorption. These are additional factorsthat might lead to plantar fasciitis.

Some physicians feel that the small nerves that travel under the plantar fascia on their way to the forefoot become irritated and may contribute to the pain. But some studies have been able to show that pain from compression of the nerve is different from plantar fasciitis pain. In many cases, the actual source of the painful heel may not be defined clearly.

Symptoms
The symptoms of plantar fasciitis include pain along the inside edge of the heel near the arch of the foot. The pain is worse when weight is placed on the foot. This is usually most pronounced in the morning when the foot is first placed on the floor.

Prolonged standing can also increase the painful symptoms. It may feel better after activity but most patients report increased pain by the end of the day. Pressing on this part of the heel causes tenderness. Pulling the toes back toward the face can be very painful.
