Hello, in the last 2 years I have experienced 3 episodes of extreme nausea and faintness. It seems to be related to pain. However, I have always been good with pain till now. The first time was when I accidentally stabbed my hand with a wine glass stem, the second when my fingers became incredibly cold when snowboarding and the third today when I slipped on an outside step. What happens is that I begin to overheat quickly, and get a cold sweat, which is followed by shakiness in my hands and arms, I feel incredibly weak and unable to walk at a normal pace, or even slowly without feeling exhausted, then I start feeling faint, with a huge feeling of throwing up. My vision doesn't seem to keep up and all I can think is 'I have to find somewhere I can sleep'. Today I was away from home when I slipped and I felt so nauseous I considered sleeping on the curb, the only thing that stopped me was the fact that I didn't want to alarm anyone. I could barely take myself home. However, once I lie down for 5minutes the nausea fades, I feel cold and hot for at least 10 minutes afterwards but then suddenly it's gone and I think 'oh how silly'. I have Factor 5 Liden, but have never had a clot, I have been on the Noriday pill for 5 years straight, I am 22 years old, female, no allergies, never had surgery. Anyone have any ideas?
