My son, 22 years ago, has been doing a lot of running and is experienceing pain in the bottom center (toward the outside) of his foot. a doctor from FootHealers suggested tendonitis or slight bone fracture and told him to rest it for six weeks. He did take an xray but said he couldnt tell from the xray. how do you know which? and what do you do to heal it? Shouldn't he wear or boot or do something to aid in the healing other that rest it? Should he get a second opinion and if so, what kind of doctor do your recommend. He plays college soccer in the fall and wants to heal as soon as possible.
