It sounds weird, but the best I’ve found is running. When I’m in running season, I tend not to get back spasms, and if I do they are mild and only last a day or two. In the winter when I don’t run, a back spasm hurts like hell for a week or longer. I’m guessing it’s my shoulders moving up and down with each stride? I don’t know, but something about it helps immensely.
