Pin worms

Hi all I got seen my a dermatologist I don’t even know what to believe at this point anymore, I’ve been being tossed by seen by different doctors etc. I had a break out with bunks and now the dermatologist is saying I have pin worms? He did a tape test, and said my bumps and rash is as because of pin worms, and I had another dr tell me I had genital herpes because of my bumps.

I don’t even know what to believe and feel like the doctors don’t know what I have and are telling me different things.

I have been extremely constipated but have not seen anything in my stool
