Last night i got a red spot on my arm
i thought it was from an old tick bite i got in may
but now i have a whole bunch of red itchy spots on both my left shoulder and left foot
they are close together and look almost like mosquito bites
and they itch like **** **** ** *

but the problem is that there's no mosquitos here and the last time i even saw one was weeks ago so What could this be ?
i'm really worried about this
