I have a friend whose husband has been having some issues that are stumping everyone. sweaty palms, major headache, dizzy, weakness, light headed, back of neck hurts. They have done a CT Scan and most lately a heart monitor (no results to this yet). He had heart surgery as a young man. When he has these episodes sometimes 3-4 a day he feels like he is floating and not in his right body/mind even though he knows everything that is going on.
