My feet, shoes, and toes are swelling to the point I m having to wear larger shoes than normal. My feet are constantly feeling like they are burning or going numb. My toes hurt. I have had stress fractures, in the metatarsal bones, of my right foot, on 3 separate occasions. I have elevated , pout ice on, and rested my feet. I have also worn my boot for the broken foot, all to no relief. What do you think it could be?
