Nearly every morning I develop a red, blotchy rash on my neck and chest within around half an hour of waking. It's happened for a couple of years now, and I originally thought it was stress-related hives but it happens all the time, even on holidays when I don't feel stressed.
Is there anything it could point towards and is it worth going to the GP about?
It's red, flat, blotchy and feels quite prickly.
Thank you
