I did something to my back-I think! All I know since about 7:30 tonight I hurt on my left side but not the whole side-it is hard to describe it exactly. It really doesn't "feel" like my back but not sure. I have had back pain on & off since I was 13 but this feels different. I hope it is better in the morning or I may be making an appointment-this is kind of crazy because it is making me feel queasy.
