What is a common sign of plantar fasciitis?

A common sign of plantar fasciitis is heel pain, particularly noticeable in the morning or after periods of inactivity, such as sitting for a long time. This condition occurs when the plantar fascia, a thick band of tissue that runs along the bottom of the foot, becomes inflamed or irritated. The pain typically is sharp and can feel worse with the first few steps taken after resting, as the fascia tightens up. Over time, the discomfort may lessen as the foot warms up, but it often returns after prolonged activities or after sitting for extended periods. Recognizing this specific pattern of pain is essential in diagnosing plantar fasciitis and distinguishing it from other conditions affecting the foot and lower extremities.
