Whenever you walk or exercise, you place high amounts of stress on the heel of your foot.
While your feet should be strong enough to handle a very heavy load, it’s possible that you could place too high of a load on your feet over time, which can bring about heel pain like plantar fasciitis. Heel pain can occur for any number of reasons, which extend from wearing shoes that don’t fit properly to playing sports like football and basketball.
Most cases of heel pain should dissipate on their own. However, continual use of a sore heel usually leads to a worsening of the pain, which you should try to avoid.
