I have scoliosis, but i've stopped going to the chiropractor for the time being. I am a college student and carry a lot of weight on my back (from books and the such). I've had a lot of back pain recently. Lately though, i've noticed my left hand and lower arm going numb. I can squeeze my hand for awhile and it will go away after a few minutes. Is this normal? Is this related to my scoliosis?
