I injured my foot a week ago Saturday. There is severe bruising on the sides of the foot, and moderate bruising under the arch. X-Rays show no broken bones. I have elevated my foot, and applied ice, and have used espom salt soaks. Now after I get out of bed, putting pressure on the foot causes me pain, and then my foot starts burning. The doctor gave me a dose of 800 mg or ibropfen, but it doesn't seem to help. Do I need to go back for another x-ray, or what can I do to relieve the pain?
