I have sensitive skin that can easily react to temperature change, heat, stress, anxiety, embarrassment, and sometimes even touch. Red blotches/marks appear on my face, neck, and upper arms. It appears quickly and takes a while for it to go away. It is not anxiety centered, like it used to be. What is the medical term for this kind of thing? Please don't just state the obvious like calling it flushing or whatever. There are medical names for these kinds of things.

Only dermatologists or doctors can provide the proper medical term for your symptoms. They will closely examine your skin and rule out the right term for it.

But I do know that skin turns red as blood flows through the skin. Heat, anxiety and stress plays a role in this also. If your stressed out, try to relax. When your relaxed, the redness usually goes away.
