aids sorry for the bad news
Well, were you bit by a spider?
usually spider bites leave two small holes and a giant red area surrounding where you've been punctured. Depending on where you live it could be a chigger,mosquito or some other bite. I suggest taking a antihistamine to help with the itching
no, that's a hairy arm with a red dot on it
excuse me, my knees aren't on my arms
I would assume a mosquito, but I'm pretty sure it appeared today and I've been inside all day.
