Im a healthy 19 year old girl with no medical history or problems. However 3 days ago a small red rash appeared on my neck and has been spreading around my neck. No other area is affected. Is there a reason that could cause just a neck rash? It does not itch and is not raised or dry. It is just an accumulation of red dots. Is it possible it is a stress rash and is there any treatment? I appreciate any answers that I can get.
