Sounds s*** man. What is it that's up with your back?No idea, as my MRI scan yielded no results.
Basically my back and neck are in constant pain and it hurts to do basic stuff like carrying a bag of shopping. Also I have constant pins and needles down my right arm, which has also happened since the back/neck pain.
You ever been to a chiropractor? I used to have horrific back pains, mainly due to nothing more than an imbalance in the muscles around my back and neck, basically pulling on the spine as I grew as a kid an just in general later on. Did absolute wonders for me. Over a period of time he 're-arranged' my back. Starting off a couple of times a week and then less and less over time, correcting my spine I suppose. I stopped going a while ago now and its getting worse and worse again.
Yours may be something totally different, like. But the general health of my back, especially my upper spine, shoulder blades and neck, contributes to loads of other things.
They are canny expensive depending where you go, probably £30 a session now. But if it works for you its proper worth it. May be worth popping along for an initial consultation.
