You problably had an ingrown hair...or just a plain 'ol zit with the borders inflamed. Clean it out with Hyrogen peroxide, put Neosprorin on it and the bandaid you place over it....so I don't think you need to plannnin a vegas run and blowin all your life saving as of yet...or you can just use that as an excuse and do it anyway.
Ringworm isn't exactly a "worm", it's a fungus, same fungus that gives you athletes foot, jock itch and ringworm: fungus called Tinea - Tinea Pedis, Tinea cruris, and Tinea Corporis (respectively).
