I have been having much worse back pain the past two weeks than I normally have. I usually have discomfort, and that's from slouching, which is from the size of my chest. But lately I have been having pretty bad cases of spasms. I can't even wash a few dishes without it tightening up and then I cannot release the tension. Also, with the back pain, comes sharp pains in my spine. What is that? When I'm having the spasms, I can barely breathe.
