Hi, I'm 24, a former ballet dancer (stopped when I was 16) with a stress fracture in the second metatarsal of my right foot that has not healed after 3 years of treatment and a possible new stress fracture in my left foot from over compensating. Why is it that my feet aren't healing and keep fracturing? I don't do any strenuous exercising like running or jumping. I have had blood tests to rule out any diseases and vitamin deficiencies, and I am at a healthy weight of 140lb for my height 5'5. I don't know what else to do. I also suffer from arthritis in my right big toe, left knee and left hip. I keep falling apart and don't know whats wrong with me. Any ideas of whats wrong with me or any suggestions are greatly appreciated.
