I have degenerative disc disease and this sounds like what I have had to deal with. When I have had a pinched nerve in the neck I have pain in the arms (either side) tingling in the hands and fingers, pain in the wrists, right now it's in the left) When I have it in the lower back I have trouble sleeping on one side or the other, depends on what vertebrae is pinching what nerve. Tingling in the toes and pain down the leg. Sometimes I can't climb stairs, I have to pull myself up, my knees don't want to work and I can't sleep because of the pain that goes down the leg. Then other times I'm just fine. Fleseril makes me dizzy and I can't function to take care of difficult child. So I take a general pain pill and keep on going. I take a bit stronger one after husband is home at night and he takes over while I crash! But I do know what you are going through. Life can be miserable when there is pain and you can't sleep and you can't do daily activities and nothing seems to help.
I've had three surgeries on my neck alone, they said they can't do any more because of the scar tissue. Right now I'm waiting another MRI on my neck next week, I think there is just inflamation and arthritis causing the pain the left arm. But a brace seems to help, geeze I hate wearing that thing!! But it does help!
Good luck with the chiro, I hope that helps!
