I have really sensitive skin. Stress, heat, extreme temperature changes, as well as a few products, make my skin really blotchy and red. Sometimes, my skin is even sensitive to touch. I used to think that it was solely an anxiety thing, but it happens with just the slightest amount of stress. Sometimes it goes away within a few minutes; other times it won't go away for about 20 minutes. It occurs on my arms, chest, neck, and face. I'm wondering if there is a general technical term for this kind of condition. For some reason, I think it would make me feel a lot better if I actually knew what it was called. Also, i'm wondering if it's possible that it was caused by something I did in the past. (i.E. Overusing products not meant for sensitive skin or excessive sun exposure).
