I did my first shot (glute) on thursday (not sure if this is part of the cause but, I might as well put it in) and that night I woke up in the middle of the night with this bad pain in my mid back, right next to my spine, on the left side. It really feels like it's my back not, my kidneys cause when I bend is when it hurt. It hurt like a SOB. Then when I woke up in the morning, it kinda went away as the day progressed. Then, the next night, same thing and this morning it went away again as the day went on and as I moved around and what not. What the hell is this? A pinched nerver perhaps? I am making another appt with my chiro to see if he knows but, I wont be able to get in until next week if I'm lucky.
