I have been having some hormonal problems, low normal thyroid and low testosterone. I'm a 22 year old guy. I often pass out under stressful conditions. For example. 4 wheeler wrecks, smashing my finger with a hammer, or sometimes just under prolonged mental stress I'll get woozy and come close to passing out. It starts out by a strong feeling of nauesau ( sp?) then ringing ears and tunnel vision and I break out in a heavy sweat, and if I don't sit down quickly, I fall flat on my face. And during this time I'm pretty much incoherrent. It hits me really quick. Iv'e come to learn that I have about 10-20 seconds after flipping my 4 wheeler over to get it flipped right side up and shut it off, then I'm gona go out. This also happens when I get severe pain from something, the 4 wheeler wrecks pretty much just scare the crap out of me but don't contain much physical pain. So it happens really quickly after a physical injury, and i'm always feeling on the verge of it after prolonged mental stress, and a couple of times it has hit me full force from mental stress. does this sound like a addisonian crissis?
