Would normally head straight to the doctors if i had a problem but am going back to uni in a couple of days and have exams soon, so i really don't have much time to make an appointment etc.

I am a 20 year old male student. I have a large red circle on the center of my chest about 2 inches in diameter and at the level on my nipples. The area isn't very red, looks like it might be almost sunburn or skin thats about to peal. Doesn't itch, isn't raised, doesn't get bigger or do anything. Seems to be the only place like it i have, been there a couple of weeks now, not really sure how it started/ where it came from.

Doesn't seem to go anywhere, but is annoying. Do you think it might be dodgy that i need to get checked out?
