I'm sorry to hear your having so much difficulty, hang in there! I followed my OS to the T and didn't push myself with the PT. Maybe your OS is keeping you off it due to the location, my break was almost in the middle of the bone, I was told that had it been close to the joints my recovery would be harder and slower, so in a way I was one of the lucky ones...I also went to general nutrition center and bought bone health suppliments, multi vitamins, and glucosamine/condroiten suppliments and those seemed to help me heal faster also. I wish you the best and happy healing!
