Random red rings/circles appearing/disapearing on stomach
I am a 22 year old male in good health. Over the last month or two I have had dime sized red rings and half moon shaped appearances on my stomach. There are usually 3-5 of them and they have been very close to identical and in the same spots since the first time I noticed them. They are gone by the morning and I usually notice them after work before I get in the shower. They are not raised, itchy, painful or bothersome at all. Cant find any information online regarding this but hopefully someone has some insight.
Here's a few pictures of the rings
"Half Moon" 3 of them not complete circles
They are always in the same spots, and the same shape in the same spot each time Ive noticed them.
Thanks for the help!
