Hi everyone, this is my first post here so please bare with me. My ball python has been making a clicking noise when she breathes, and has been yawning frequently. There are no signs of mucus anywhere in her mouth (pic of her yawning here) or on the sides of her tank so I don't think its an RI. There's no mucus bubbles in her nose either but her nostrils look crusty, leading me to think that it's stuck shed in her nose? When I got her from the pet shop she had stuck shed all over and the conditions they had her in at the pet shop weren't great, so that's also why I'm thinking maybe she has scales stuck in her nostrils?? I took her to a vet and the vet said she was perfectly fine and healthy, but it's obvious that she is still having some trouble breathing (clicking, open mouth breathing, yawning frequently). I don't know what to do. I wasn't sure how to add a picture so I linked one here. Please help!
