Zach, thank you so much for doing that research!! I looked at the photo posted, but my BP's is a bit more red and it looks almost like there is dried blood inside and a bit outside his heat pits and nostrils. I was looking at older photos of him and his heat pits were white/slightly pink. So I think I'm going to wait a bit longer till after he sheds and then if it's still there I'm going to take him to see a vet. Thanks
