The basics
What It Is & How Common It Is
Pain underneath the heel—often worse with the first steps after sleeping or sitting—commonly involves the plantar fascia, but not every case of heel pain is plantar fasciitis.
Plantar-fascia irritation is one of the most common causes of pain under the heel. A typical presentation is pain with the first steps after rest that eases as the foot warms up, then returns after prolonged standing, walking or running. Rapid activity changes, hard surfaces and limited foot or calf capacity may contribute. Heel spurs can exist without symptoms, and focal bone pain, nerve symptoms, Achilles pain and inflammatory or systemic concerns should be considered when the pattern is different.
