Hi

Am 20yr old male who is healthy, I have noticed for a while now that when i am cold and get warm quick my neck and chest go red its NOT itchy, sore or dry skin it just red but it wll go after 20-30minutes. Also it sometimes happends when i get nervers. I have noticed it alot more in the past week i have had it for awhile but it has shown up more dont know if its from the cold weather now. I dont feel ill or anything like that.
