I have a pinched nerve in the neck and shoulder . my arm is in alot of pain.. I have alot of knots on my arm . don't know if it's the nerves or the muscles or all up above..the elbow is extremely sensitive to touch the whole arm is so sensitive even when the wind would hit it , it hurt so bad..I run my fingers down my arm and it is even my veins are in like little beads..waiting to get a cortisone shot but that's not till Nov . 30. I can't deal with this pain.
