So currently, as one of my previous posts says, Prometheus has extremely smelly, runny poop. From research it's most likely he has pin worms.
I hear that going to the vet is cheap for a fecal exam, but it honestly varies at each vet. Here in PA, I'm assuming that it'll be more expensive since there are so few Herpetologists.
There is a website, recommended by someone on here on another forum, called bugs de lite. Or something like that, and they have a pinworm treatment that is highly recommended. If I ordered this for him and gave it to him, Would it be harmful is he doesn't have pinworms?
Pinworms can be treated effectively with Panacur. I'd have a float done or check out a fecal sample under microscope to determine which parasite is present and how intense the infection is. You're right that the costs vary from vet to vet. My vet charges $36 for a visit and $25 for a fecal exam. Bug De Lite is Tracie's site. She is one of the moderators on this site (Drache613). Panacur is relatively mild so it's not likely to cause harm but I still think it's best to first have a test done to see what you're dealing with and to what extent.
