My chest/neck breaks out in red blotchy spots when i'm nervous/excited. no itching, but i get very hot. anything i can do to prevent this? thanks!

Maybe: With nerves there are some techniques that may help when it starts to occur. Look up, and learn to use a few breathing techniques. Come up with a calming saying or prayer you can say to yourself to help you calm down. Not sure i'd suggest med tx unless it's a big problem for you. Consider this too: is it a huge deal? Accepting that it happens might take away some of the anxiety & even decrease sx.
