I once developed shingles and because I was way too young all of the docs who were my friends and family members who took at look told me that I didn’t have shingles. But because it didn’t go away and it hurt like hell, I finally went to the dermatologist, who walked into the examining room and from across the room took one look at my arm and said “You’ve got shingles.”
And of course she was right. I did. Even though all the other docs — none of whom were dermatologists — were sure that I didn’t.
Basically they didn’t know shit about shingles.
I’m not sure there’s any way around it.
Going from doc to doc to doc to try to get an appropriate diagnosis is frustrating. I’ve done that too.
They all know different stuff. Hopefully, one of them will know something that’s useful to you.
