What is a common sign of plantar fasciitis?

A common sign of plantar fasciitis is pain in the heel during the first steps in the morning. This condition is characterized by inflammation of the plantar fascia, the thick band of tissue that runs across the bottom of the foot and connects the heel bone to the toes. The reason this pain is particularly noticeable in the morning is because, during the night, the plantar fascia can tighten. As a person gets out of bed and takes the first few steps, the tissue is stretched, often leading to sharp pain in the heel. This symptom can also occur after sitting for a prolonged period, as the fascia tightens and then is suddenly required to bear weight again.

Swelling of the ankle, inability to move toes, and weakness in the quadriceps are not typical signs of plantar fasciitis. These symptoms may indicate other conditions or injuries that are not directly related to the inflammation of the plantar fascia. This helps differentiate plantar fasciitis from other disorders affecting the lower extremities.
