For a couple weeks now, I've been very stressed out. I noticed a while ago that my back has been hurting very bad (in the middle, mostly upper). I'm guessing it's been from not eating right, not getting enough sleep, not having energy, etc. At one point it hurt to even move because of it, but after that it seemed to let up some. It's been acting up again lately and I've been wondering if I strained my back and what you can do for it. I've already tried the heating bad, but it obviously hasn't been working. Please help! Thanks!
