What is a classic symptom of plantar fasciitis?

The classic symptom of plantar fasciitis is pain in the plantar surface of the calcaneus, which is the heel bone. This condition is characterized by inflammation of the plantar fascia, the thick band of tissue that runs across the bottom of the foot, connecting the heel bone to the toes. Individuals often experience sharp, stabbing pain, particularly upon taking their first steps in the morning or after prolonged periods of sitting. This discomfort typically decreases with movement but can intensify after extended activities.

Other options related to pain in the Achilles tendon, pain with dorsiflexion of the ankle, or pain in the lateral aspect of the foot do not align with the hallmark characteristics of plantar fasciitis. Each of these symptoms could suggest other conditions affecting the foot or ankle, highlighting the importance of recognizing the specific presentation associated with plantar fasciitis for accurate diagnosis and treatment.
