I bent over earlier on to turn my laptop on at the wall and got this stabbing "nerve" pain towards the bottom of my back. I struggled to walk around the block with my dog earlier and found that bending over and then straightening helped a little. I then decided to "walk through the pain" which seemed to loosen it a bit. I'm sat down now and just had another shoot of pain.
Any ideas what I might have done and how serious it is? It's that pain that makes you take a sharp intake of breath. I've got a session at the gym this afternoon with my Personal Trainer which I don't want to miss so I was wondering if exercise would help? Maybe an Ibuprofen?
