Hi, I had my 13 yr old son in for his school phy. I told his new doc about a bull's eye rash he had when he was a little over 1 yr old. We took him to an ER at that time and they said "it's not LD". His new doc said other things can cause a bull's eye rash. He also said LD can sometimes clear on it's own, and that the ELISA is actually more sensitive than the WB. My question is is any of this true? Some of it?
