Hi can anyone tell me what they think this is?

hi i developed this rash yesterday luckily it went away today but still wondering what it could have been. looks weirdimage

Hello there, I think that is ringworm. I googled and some pics look the same. Very unusual pattern.

Ringworm doesnt usually last such a short time,so I have doubts about that. Are you in an area where there are ticks? If you start feeling unwell then do try to get a call to your doctor. Email the pic to him.

yes i live in Montana and im outdoors a lot, but i didnt think a bullseye would disapear that fast. but this am i woke up not feeling bad but not amazing either.
