Stress related rash

Bonita

Hello everyone. I get this sometimes all over when I get stressed out. I have anxiety and this rash will happen if I’m in a crowded store or if I’m in a sudden stressful situation. It itches and burns. I went to a dermatologist a couple years ago (this has been happening for a long time) she had me start a histamine blocker and it usually helps but sometimes I’ll still get the rash just not as itchy. Anyone else dealing with something like this? I also have really dry flaky skin on my face. 😩
