Im very unsure of what to do, I was injured when I stepped up thinking I had cleared a steel beam, I had no pains for 2 days the when doing my regular routine i started having sharp pain while breathing inhaling and exhaling. I went to a spine clinic they referred me to a physical therapist, I have constant pain on both sides of my t9-t10. after months of PT still the same pain. Had exrays and mri done they all come back as clear...? Im not on pain meds, just want to get to the source of the problem..any ideas ?
