Yesterday I went to the chiropractor to see the results of my MRI. He told me 2 weeks ago that he thought I would be ok to go back to jiu jitsu. After six months of resting from contact sports I had no healing from the last MRI. This means that my disc herniation happened more than a year before I got my MRI 6 months ago. My chiropractor told me that if I want to act intelligently then my jiu jitsu career is over. If I avoid sparring, he said that krav maga is ok.
