Dh pulled a tick off of his belly the other day and now he has a small red bulls eye type of rash that seems to be spreading. He feels fine and hasn't complained of any discomfort so I was surprised to see it there tonight. Should we be worried and heading to the dr tomorrow? Anyone have any experience with these nasty things? I know lyme disease is nasty but he's not exhibiting any signs of it so I hate to jump the gun.
