Every once in a while I will get an awful ache in my lower back. I think it is just muscle pain from having bad posture or straining myself. Usually it goes away within half an hour or so. Stretching seems to help, drinking lots of water doesn't seem to have an effect, which is why I think it's muscles and not kidneys or something.
This morning I woke up with this kind of pain, though, and it's still there two hours later. :( Aaaughhh. I think it's just from exercising hard yesterday without stretching my back at all. I'm normally very sedentary.
Anyway, usually when this happens, including today, the pain in my lower back will "migrate" down and my testicles will ache, too. Is this normal for lower back muscle pain, or might it mean there's some other problem besides cramps and spasms?
