I am a 31 M who recently fainted for the first time (12/5). I saw my wife faint while she was at the hospital and 2 minutes later i fainted. I fell hard according to the nurses and hit the floor, my head bounced off. Since then i have had a bunch of symptoms and not sure if it s just a concussion or something else. They took a cat scan right after it happened and every thing looked good they said. since then my symptoms have been....... Confusion, headache, tingle sensation on the left side of my head, weakness on and off in my legs (inability to walk twice) nausea, heaviness in my chest, a pins and needle sensation in my head, and neck, a few times during the day i get an ice cold sensation in my feet and hands, lethargic feeling, wake up gasping for air,
