I believe I develop miliania (heat bumps/heat rash/prickly heat) very VERY easily. If I am in a tanning bed for 10 minutes, exercise/workout for minimum 5 minutes, or am outside in 70+ degree Fahrenheit weather for just a few minutes my skin reacts oddly.
I should mention I do not sweat easily, never have. I don't have the need to wear deodorant, I just don't sweat.
However, if I do any of the above listed activities, I get clearish-whiteish bumps ALL OVER my chest, stomach, back, and arms. I've never gotten them on my legs nor face. If I scratch them they pop easily and just clear liquid like sweat comes out. Sometimes they don't go away for a day or so if I don't pop them.
It's like my skin can't sweat properly, it always gets trapped. Why would that be? What causes this? What can I do to prevent it? Is there any skin disorder that causes sweating problems?
