It really depends on what the source of the pain is?
Is this a muscular injury, like a spasm, or a nerve/disk/vertebrae problem?
If you aren't sure, you should go get checked out.
I was having major back issues for the last few months, with my muscles spasming and locking my back into place. Turned out it was a sprain in the insertion of my hamstring and the muscle tightening was pulling my spine out of place and locking it into spasm around a nerve cluster. Fun.
I've done massage,Chiro, theta healing (like Reiki, but faster), yoga stretching and also some supplements (glucosamine, calcium and vitamin C), which can help with muscle spasms.
