About 3 weeks ago I woke up on a Sunday feeling fine. After about 2 hours I started having back pains. As the days went on my back pains got worse. The pain started in my upper back and neck. On Wed. my left arm went numb. The pain was getting worse as the days went on and I wasn't able to even sleep at night. I ended up going to the ER (recently left job and not insured). Had several x-rays done. DR said I had several herniated discs in my back, gave me medrol dose pack, and norco, and sent me to see another Dr. It's been a week since I've been off the medrol, and all out of norco. I know I have a pinched nerve because I have no feeling in my left arm. Is there anything I can do to fix this myself? How long should I expect this pain to keep going on.
