Me and my friends did the salt ice challenge. We all did it for a minute but when we released the ice it was all puffed up. After a day of itchyness my friends got left with a scar. But my spot turned into a red, bumpy, itchy circle. Could it be possible I have ring worms? I know they're not actual worms, but it sure is suspenseful and disturbing to think I have fungus growing on my. Someone help?!
