Heel Spur
A heel spur is a common condition where calcification occurs in the plantar fascia at the heel bone. This can lead to inflammation beneath the heel, known as plantar fasciitis. Plantar fasciitis is a painful irritation at the point where the plantar fascia attaches to the underside of the heel bone. With prolonged inflammation, a bony protrusion may form at the attachment site, which explains the term “heel spur.”
