No bulls eye rash and it's been about a week so I'm good on that. The one on my shoulder hurt up until yesterday (about a week); the one on my stomach just sort of scabbed over. I did have a bite a few years ago that I didn't get treated and it did bulls eye (second time I got the rash). I figure, at this point, do maintenance. lol Still haven't bought the astragalus. Oi vey.
