Symptoms & Signs. Pain in the heel can result from a number of factors. Abnormalities of the skin, nerves, bones, blood vessels, and soft tissues of the heel can all result in pain. Because of walking and daily movement, we are always at risk for injury or trauma to the heel area. Common causes of pain in the heel include blisters and corns. Plantar fasciitis, inflammation of the bowstring-like tissue in the sole of the foot stretching from the heel to the front of the foot, is one condition commonly associated with heel pain.
What are the causes and symptoms. Plantar fasciaâthe band of connective tissue on the bottom of your foot that stretches from the heel to the ball of your footâsupports your footâs arch. If this tissue becomes inflamed, youâll generally feel the pain in your heel. Eventually, hook-shaped calcium deposits, also known as bone or heel spurs, may form on your heel bone and cause further pain. Structural issues with the arch of your foot can lead to this cycle of inflammation, spur growth, and pain.
