Twice today I was sitting and all of a sudden both arms went numb I couldn't feel my hands or use them the were totally numb.after I laid down after a few minutes the feeling came back.my hands were shaking.I thought a pinched nerve but I'm not sure now.I do have nerve end damage in my neck.but I always just get tight muscles and knots I only take ibprofin for pain.im not sure if I should go to the emergency or just make a doctors visit?
