I am an avid runner (well, I was until I got injured) and was diagnosed with a tibial stress fracture in early January. I'm pretty sure the fracture can be attributed to overtraining and biomechanical issues. I spent the next 8 weeks doing stationary biking patiently waiting for my fracture to heal so I could get back to running. Throughout this time, I had all sorts of pain around the fracture and in my lower leg. After the 8 weeks, I went back to the doctor for a followup X-ray which showed calluses along the original fracture. Over the next week, I began having extreme pain around the fracture and ended up back at the doctor for another X-ray. This time, to everyone's amazement, the X-ray showed a clear fracture line and no callusing, just two weeks later. They determined I was vitamin D deficient and this would explain all the pain and lack of healing. The orthopedist put me on crutches for a month and I'm due back in late March for another X-ray. When I spoke to my physician (internal medicine) about this he seemed somewhat doubtful that a vitamin D deficit could cause all this havoc.
I am interested to know what others think about this issue. Any and all feedback is welcome! I am willing to do just about whatever it takes to be able to run again... this was a big part of my life prior to the injury and I am saddened that I can no longer participate.
Thank you in advance.
