I was bitten by a tick on 5/23/2015. it has been 3 months now, and every now and then, the site of the bite (my left-side collarbone) will turn red and start itching again, then go away a day or so later, looking more like a scar. I still have the tick frozen in a ziplock bag, and it still has his head attached to his body, so I dont believe I have anything still in there. Any suggestions?
