Don't go all Chris Benoit on us. It's just back pain!
But seriously: it would help to know exactly where the pain is located, is it unilateral or not, does it shoot outwards, and if so: to where? Etc. Those are what my physio kept asking me, not that you get the impression I know WTF I'm talking about.
If I just arch my back it shoots pain dead center, but when I'm out walking around it will shoot on the left or right, particularly on the side if I step down with, like off a curb or something.
When I performed a squat movement yesterday, it hurt like hell all over the lower back. The neighbors must have thought I was slaughtering a donkey in here.
Yes with a back injury the slightest things will cause pain like tieing your shoes. I injured my back years ago doing deadlifts, it still flairs up now and then. The only relief I got was from a chiropractor aligining the spine. Now when it flairs up I can "pop" my back on my own much like a chiropractor does. Ibuprofen works for pain.
I get a pinched nerve or something a couple times a year under either shoulder blade, and ya it gets brought on by the damnedest things, like moving a ladder or something lame. I can still lift things ok it seems right now, like the dog because he's too old to jump into the van, although I haven't tried anything heavy. Seems like more of a posture problem.
I'll consider a chiro too if it doesn't start healing up. And ya I went to the pharmacy and loaded up with drugs. Currently running a 2 painkiller w/opiates + Jim Beam stack.
