My husband for a week has clamy skin then real cold, jitters, he had EKG, Labs,Chest x-ray, bilateral carotids and all came back normal. He is about to have a nervous breakdown, if he doesn t get answers. It will wake him up if he s sleeping and he s not been able to sleep. I don t know what to do for him. He has only been in a hospital once, at that time 10 years ago he had 2 stents put in one artery.He never is sick and is not handling this very well.
