1. Go to Home depot and buy one of those back braces that the workers are supposed to wear. Put on a T shirt and wear that brace for the next week ( 24 hours a day) or untill you back gets better. That is what I used to do. As soon as I get that twinge in my lower back I put it on and usually within 3-4 days My back is fine.
Really good advice, I have one of these, I think it was for weight-lifters, and it does work!
