Mystery Bumps

I have a few little red bumps on me that I would normally say are a bug bite of some sort but they haven't gone away of the last couple of days (like bug bites tend to do) so I am thinking that I might have touched something in the yardwork I was doing that I am slightly allergic to....took a benedryl last night and the itching went away but I still have the little bumps....sometimes I hate a good mystery.
