it certainly sounds like ringworm. this will not go away on its own!
i got 2 perfect round completely red circles on my back possibly ringworm? occasionally i get an itch but nothing bad. . i noticed the other day i had 2 completely red perfect circles on my back they look to have really little pimples maybe blisters on them my first thought was ring worms but i havent seem and thats completely red most have a ring like fade to them although i have read it can be solid red havent had any sickness or anything with it just an occasion itch but rarely brother thinks maybe masquito bite but i just wanna make sure so if i know to buy the cream or what not. .
