Should I go to urgent care?

I posted last week about being eaten alive by mosquitos  Sunday July 31st. (in Omaha NE) and my itchy bumps were calm all last weekend then yesterday out of now where a few of them sprang back to life and are itchy again! One of them is red around the bump and about the size of a half dollar. 
Of course I'm paranoid about Zika, but this makes me more worried as I've never had a bite do that before. I've always been pretty allergic to mosquitos and they make me itch something fierce, I also haven't had a bite in about 4 years due to living in SoCal until May of this year. So maybe I'm just MORE allergic now? Help!!!!
