Ringworm is a fungus. Petlover, get some Lotrimin and apply it religiously (every day for two weeks). If that doesn't clear it up, then go see a doctor.

Until then, do not touch it and touch anything (ANYTHING) else without first washing your hands with antibacterial soap. Change your pillow case often. Disinfect anything that comes in contact with it - the collar of your shirt, towels, etc., because if you don't, you'll only get it again. It is very contagious, so do not let your dogs near it, nor any of your other animals.
