I've been researching now I need some advice. I have a tens unit for back spasms, can I use that on my worst arm? And if so how? Hahahahahahaaha and over the counter medications, supplements, vitamins? What should I take? I need vit d and a multi vit but not sure what else. Please give me pointers. I hate the spread and not doing anything that requires pulling or lifting more then 2 lbs. I wanna be better even if just a little. Thanks
