Every mile you walk puts 60 tons of stress on each foot. Your feet can handle a heavy load, but too much stress pushes them over their limits. When your feet pound on hard surfaces from sports or shoes that irritate sensitive tissues, heel pain may develop, the most common problem affecting the foot and ankle. A sore heel will usually get better on its own without surgery given enough rest. However, many people try to ignore the early signs of heel pain and continue doing the activities that caused it. A sore heel will only get worse and could become a chronic condition leading to more problems. Surgery is rarely necessary.
