A heel spur (calcaneal spur) is a bony outgrowth or calcium deposit that forms on the underside of the heel bone. This condition is associated with various factors such as obesity, flat feet, and inflammation of the plantar fascia, the ligament connecting the heel bone to the toes. While often asymptomatic at rest, it manifests as pain that emerges with movement and typically intensifies towards the end of the day, making it an orthopedic condition that can significantly restrict a person's daily activities and mobility.

The most common symptom of a heel spur is a sharp or stabbing pain felt in the heel, especially when weight is placed on the foot. This pain usually increases as the day progresses and can sometimes feel like stepping on a nail or stone in the heel. Constant pressure on the foot ligaments, stress, and strain on the bones can trigger heel spur formation; walking barefoot on hard surfaces, in particular, increases this risk. Often going unnoticed until severe pain develops, a heel spur can be successfully managed with early diagnosis. The crucial step is to determine an appropriate treatment plan following an accurate diagnosis.

To alleviate heel spur symptoms, methods such as rest, ice application, heel supports or stabilizing devices, pain-relieving creams, and massage can be effective. The consistent and correct application of these methods helps to rapidly reduce symptoms and improve patient comfort.
