Your heel is the back part of your foot. A band of tissue called the plantar fascia connects the heel bone to the bones in the ball of your foot. Nerves run from the heel up the inside of your ankle and into your leg. When you feel pain in the bottom of your heel, the plantar fascia may be inflamed. Overuse, Achilles tightness, and excess body weight can cause the tissue to tear or pull away from the bone. Sometimes the inflamed plantar fascia also irritates a nerve, causing more pain.
Wearing shoes with poor cushioning can irritate the tissue in your heel (plantar fascia). Being overweight or standing for long periods can also irritate the tissue. Running, walking, tennis, and other sports that put stress on the heels can cause tiny tears in the tissue. If your lower leg muscles are tight, this is more likely to happen. A tight Achilles tendon will also contribute to heel pain.
You may feel pain on the bottom or on the inside edge of your heel. The pain may be sharp when you get out of bed or when you stand up after sitting for a while. You may feel a dull ache in your heel after you’ve been standing for a long time on a hard surface. Running can also cause a dull ache.
To prevent future heel pain, wear shoes with well-cushioned heels. And do exercises prescribed by your healthcare provider to stretch the plantar fascia and the muscles in the lower leg.
