I was originally bit in November 2011 and although I never got the EM rash, the site of the bite remained swollen, red, and itchy
for about 9 months. A couple of months ago, after it had finally healed, the bite seemed to come back (swollen, red, itchy). I thought at the time that maybe I was bit by something again, even though it seemed strange that I would get bit in the exact same spot.
It went away after a week or so, but a couple days ago it came back AGAIN!
