Metatarsalgia may resolve on its own after a few days. If your discomfort lasts longer than two weeks, or if it is severe and accompanied by swelling or discoloration, consult a doctor. Your doctor will evaluate your foot when you are standing as well as sitting. He or she will also examine you while lying down to make sure that you do not have any other problems with your feet or legs. If the cause of your pain is identified and treated, most metatarsalgias will go away on their own. It is important to see your doctor if you experience pain in your feet for more than two weeks, as this could be a sign of something more serious. Your doctor may want to x-ray your foot to look for any underlying problems such as arthritis or infection.
