I have a pain in mid rt metarsal area which arose after striking foot on pool deck while swimming. The day after the blow to the foot, I had an annoying pain, but functioned normally. After a few days my foot swelled out of control. I could not walk or sleep. 2 days ago, I went to an urgent care facility. X-rays were negative for a fracture. The m.d. prescribed 500 mg cephalexin 4 x per day for 14 days. After 2 days, I have had no improvement in swelling. The entire time I have averaged 1500 mg ibuprofen per day. I am wearing a soft shoe ans icing 4-5 times per day. I stopped all exercise 2 days ago. After 2 days, I have had no improvement in swelling, and the pain continues.
