When to worry about a bug bite?

I BET that apartment complex is infested with bed bugs,and/or termites. Bed bug bug bites can be as u describe, and some people don't itch, though many do, just keep em clean, and it will take a while for them to go away, if it was some random bed bugs, or termites..use alchohol on em, or calimine lotion. But..if u get a fever, wich I doubt,since it's already been a few days, or if they get worse...see the Dr., but I bet u will be just fine. Sucks,though, but it could be worse!
