The most common cause of heel pain is plantar fasciitis. Plantar fasciitis is the inflammation of the plantar fascia, a connective tissue that runs from the heel to the toes. This piece of connective tissue supports the arch of the foot. Pain may arise from walking too much and from structural issues, such as a high arch or a flat foot. Wearing the wrong footwear may also contribute to heel pain.
Heel bursitis is another condition that may contribute to heel pain. At the back of the heel, there is a bursa, a fluid-filled sac, that supports and protects the bones, ligaments, and tendons of the foot and ankle. This bursa may become aggravated and inflamed from overuse or from landing hard on your heels. The pain usually increases as the day goes on.
Heel bumps may further cause heel pain. This is a more common condition in adolescents. The heel bone has not fully matured. As such, it may rub and cause pain in the heel. This condition is often exacerbated by heels or flat feet.
Tarsal tunnel syndrome may cause heel pain due to an entrapped or compressed nerve in the foot. Other less common conditions causing heel pain further include chronic heel pad inflammation, a stress fracture, sever’s disease, Achilles tendinosis, and arthritis.
