For the last few weeks I have had some annoying lower back pain. At first I thought it was cramps because I was due for my cycle, but I'm now late (not preggo, I'm fixed) and I'm still having pain. I've tried sleeping on my back, adjusting my back support at work, etc. It just doesn't seem to go away. Any one else experience pain like this? It still sorta feels like menstrual cramps, and sometimes even wakes me up from sleep.
