Hi, I woke up and noticed I have a non itchy rash all over my stomach back and chest. They are small pink/red and slightly bumpy. They do not itch.?

Non specific rash. You have given a non specific description of your rash
Is it elsewhere? First occurrence?
Try over the counter hydrocortisone 1%
It may work but if it is not enough go to a dermatologist and get stronger cream to put on it at least twice daily.
