what causes heel pain in the morning
By Christine Dobrowolski, DPM. There are many different causes of heel pain, but the most common cause is plantar fasciitis (plan * tar fash* ee * I * tis). If you experience a sharp pain in your heel when you first step down in the morning, it is most likely due to plantar fasciitis. This problem is a result of excess stress through a long ligament type structure (the plantar fascia) in the bottom of the foot.
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.
