I have this rash on my skin which is intensely itchy and when I start scratching, I just cannot stop. It appears as a dark red patch currently around my groin area but I had similar itchy rash a couple of weeks ago on my neck and legs and it used to itch badly. They went away on their own in some weeks. Now I have it around my groin area. I have added some photos to show how it looks.
I haven’t yet seen a GP or dermat for this. Any thoughts on what this might be and what can help to treat it?
