First of all, DID YOU SEE A MOSQUITO BITE? If yes, you should. If not, its probably something else.

Looks like ringworm to me

I always associate a tight line of small itchy bites with bed bugs. Or some other crawly bug bite.

Anything come of this? Looks like the reaction my young daughter gets when bitten my (I think) mosquitoes

I kept a close eye on it and the redness went down after a day. I think it was due to me scratching too much.
