Got this response from a PhD university parasitologist:

Based on what I can see, it looks as if the bumps are caused by larval trematodes (metacercariae). The peeper became infected when it was in the pond breeding. Larval stages of the digenetic trematode called cercariae left an aquatic snail (wher the trematodes undergo larval development) and penetrated the frog. Piscivorous birds are the definitive hosts and become infected when they eat the infected frog. If you want to catch and freeze an infected peeper, I would be happy to look at it to make sure. I could probably identify the metacercariae to genus. Only if the metacercariae occur in very high numbers will they injure the frog. hope this helps
