yesterday while I was at my dad's house visiting with my step - mom I got bit/stung by something.... after a few hours the bump went away, it never itched, it never turned red.... I am feeling very achy today however, no fever or any other symptoms to make me think I'm getting sick again.... could this feeling be from the bite yesterday? I know we aren't doctors on here, I just want opinions ☺ I can't just run to the dr as I don't have insurance (our insurance company didn't renew our policy but continued to cash our checks, and hubby can't sign us up until October for insurance)
