Whenever I get anxious about something, I start getting itchy, really itchy, and then the scratching starts. There is nothing visible on my skin when this first starts but within a day or two as the itching gets worse, little bumps appear, same colour as my skin, barely visible to the naked eye. But then they turn pink. The itchiness is unbearable. I have scratched until they bleed and then scratched some more and more and more. I've got these patches in a few places and the areas seem to be spreading. Probably from my continual scratching. I know it's from stress/anxiety cuz that's always when it starts. My lower arms look like I have the measles, which I don't.
