Why do i get a red rashes on my neck when i get nervous?

Anxiety Rash: It's not the anxiety itself that causes a rash, but the stress caused by anxiety.Stress puts your body in a state of extreme tension, and releases a great deal of cortisol and adrenaline into your blood stream – both of which are known to lead to skin reactions.Try to take deep breathes, drink plenty of water, and do some activities that relive stress. Hope this helped :].
