Does anyone else ever get this? Whenever I feel stressed it shows almost immediately on my skin and I erupt (mainly on my neck) with a bright red almost birthmark like rash. It stings and is itchy and drives me crazy. Also when I feel it coming on I also get more stressed about it and that on turn makes it worse 
Does anyone else get this and if so how on earth do you keep it at bay/treat it?
Thank you
