Suggest Treatment For Backbone Injury

back in feb. i was in a sledding accident. i hit a tree with my back. Xrays and CT and MRI was taken. ?I was diagnosed with a compression fracture of the L 1 and a Pars fracture of the L 3. It has been a little over 3 months. The last X-rays my doctor informed me it showed no improvement.

I understand it is hard to give me exact answers with out seeing xrays and other films. but i have done everything was told to do. I have been wearing the brace that was prescribed and have been taking it easy on the lifting.

how can you tell from an xray whether a bone is healing? and im still having muscle pain and if im sitting in a slumped position i do get a little more pinpointed pain on the spine (where the injury is) i try to sit normal as much as possible. im mainly worried about whether this is normal. he is referring me to another physician but im afraid i may be getting a raw deal.
