I was wheel barreling dirt for 8 hours and almost dumped a full load. Strained to keep it from tipping and felt a muscle pull and pop. I had no pain for 2 weeks and then it began. This was 8 months ago. Went to doctor who perscribed PT. I went for 6 weeks and they said there was nothing more they could do for me once they loosened the muscles up. I was then refered to a back and spine pain management doctor. MRI shows nothing wrong. 2 steroid epidurals and no releif. I have pain in my upper left back. Some numbing sensation in my left shoulder, gets worse if I don't adjust my back and get it to relax. I have a burning pain about the size of a quarter in my lower left rib area. The pain seems to be consistant in those areas but can flare up in others as well. Sometimes the pain shoots down to my left hip, not that often though. Any ideas? The Doctor is wanting to try some experimental drug thinking I have a virial infection.
