We put a great deal of stress on our feet every day because they carry the weight of the entire body. As a result, heel pain is one of the most common problems in the feet. If you spend lots of time running on hard surfaces or if you wear shoes with poor support, you may irritate the tissues in your heel and develop pain. There are many different conditions that can cause heel pain, but it's usually categorized as either pain under the heel or pain behind the heel. Heel pain typically comes on in a gradual manner, and most people will experience pain and tenderness under the foot, towards the front of the heel. Depending on the condition, symptoms may get worse after getting out of bed in the morning, running for a long time, or when frequently wearing improper footwear like sandals or high heels.
