it really depends on where you were when you recieved the bites. if you were in the grass i would say this sounded like chiggers which are tiny little grass dwelling bugs that bite you and cause an itchy rash. if not you could be allergic to the bite of whatever it was. or you could even have scratched and caused a skin irritation from that. it's hard to tell exactly without further information. i would possibly suggest an over the counter hydrocortizone cream aloe vera gel or a good lotion and see if that helps.
i have a very itchy rash behind my knee. it started as a cluster of little bites. what is it and how do i treat it?
