First, I'm a 29 yearold Caucasian male of European decent (German/English mostly). I eat fairly healthy and do not have any known medical conditions or allergies. I have a moderately pale but clear complexion with what seems like some dry areas (forehead / temples) as well as oily areas (nose).
As you can see in the attached photo, for some years now, whenever I exert myself physically (especially if to the point of sweating) or taking a hot shower (which I avoid, but still), my forehead and temples (and sometimes around my eyes) break out in a blotchy red rash. Though my face may feel a bit warm, there is no other itching or physical sensation involved.
It appears to be body temperature/heat related as water alone (from a shower, sweat, etc.) will not trigger it, nor do foods (spicy or otherwise) or alcohol seem to trigger a response alone (though they can exacerbate or increase the likeliness of a breakout, or maybe the likeliness of feeling hot/sweating).
What seems even stranger is the skin around where the blotchiness tends to occur turns rather pale (as if the surrounding blood is draining into the blotchy areas).
Fortunately, once given a chance to cool down the rash tends to go away in 15 minutes or so and doesn't seem to leave any lasting effect. Not so fortunately, I obviously have to shy away from physical activities or anything that involves me being hot/outside/sweating/etc. That's all well and good, but it's affecting my life adversely and I'd like to do something about it.
I've not seen a doctor (can't afford to just yet) so I'm looking for any possible over-the-counter solutions (I'm well aware I should continue to avoid triggers, but I'd love to have a little more control over the situation, if not a cure). Failing that, I'd at least like to know if this is a recognizable condition with a name/treatment/etc.
Many thanks in advance,
J.D.
