Tiny pimply rash, always there but very itchy off and on

Have you been checked for other things? Scabies and shingles both appear as a very itchy rash, often on the torso, and have specific treatments.

The skin where the rash is has taken on a light brownish hue. I'm calling my PCP. Let's see what he says.

I have developed a rash 10 months out from having Covid. It is on my cheek bone and hairline.

Doctors almost always say "its dry skin". Even when my arms were covered by an angry red rash (I knew that was a reaction to wood dust and sap). They generally say that it is eczema and prescribe hydrocortisone or other anti inflammatory cream/gel. I had extremely itchy rashes on my arms and legs for many years, like tiny water blisters. In my case it was gluten and it went away within a few months of gluten free. You might consider an elimination diet. I also got facial acne after covid and that doctor prescribed metronidazole gel (worked, but took a few months). If I live to be 100 I'll have quite the illness collection, not as much fun as collecting chocolates.
