So I've been having these 'episodes' (twice in the past), where I feel tingly all over, break out in a cold sweat, and get a little light headed. Never passed out before last night. Went to walk from the stove to my sink since I felt like I was going to vomit, and never made it. All of my blood-work etc. came back normal so they released me and told me to check in with my doctor. I have a nice bump on the back of my head where my ceramic tile floor caught me, and my shoulder seems to have taken most of the impact as it hurts like hell. I've been eating and what not. So they couldn't really tell me what caused this. It happens sparatically and kind of hits out of no-where. So we shall see what the doctor says when I see her. Just would be nice to know why I'm having these 'episodes'. I'm not a diabetic, no history of seizures, etc. Any thoughts?
