My doctor at Lewis Pain suggested me glucosamine sulfate supplement for back pain. It builds cartilage and tissue to support spinal disks. It would be better, if you will consult your doctor for the best food and supplements.
You need rest and cold compression, try a ColdCure, cold compression, wrap to get deep inflammation down which could be the source of the pain. A blood flow stimulator (BFST) will speed up the healing process if you have any soft tissue damage too.
