Waking Up With Dead Arms

For the last 4 months I've been waking up with dead arms and numb hands but not like pins and needles more like pain and burning and they dont quite wake up. They remain stiff and uncomfortable all day. I have unbearable pain down my left forearm. Both forearms were stiff and then I did something that wouldnt ordinarily cause this kind of pain that wont go away. Also, the bone on the inside of my elbows hurts as if they were bruised and if I bang my arm I see stars its so painful. My blood work is all normal. I went to a Neurologist because I also feel some numbness down the left side of my back and they are wanna do an MRI. My Psychiatrist asked me why my elbows were so red and I had no idea why. He told me to get it checked out. He never ionformed me of these possibl;e side effects. He knew Ive been uncomfortable and in pain for a while. When I started reading these posts, I quickly called him. He was in traffic and couldnt speak to me. I'm so nervous I have permanent nerve damage.
