@Eviemae - I live in an area that has seen many cases of Lyme Disease caused by tick bites, and our doctors almost always seem to treat the illness quite seriously.
They don’t mess around with it. I’ve have seen more than a few folks go into the hospital for days or longer so that they can be properly treated for Lyme Disease, even if the doctors were not 100% sure that it was that initially. If the tick bite symptoms seemed to idnicate Lyme, the patient would be treated that way.
Then if turned out to be the other after testing, at least the sick person had been getting adequate treatment all along.
