I've noticed ever since I got my ball python, he has been making wheezing noises. I read online that it could be an upper respiratory infection and that I should increase the temperatures in my tank. I raised the temps. I also gave him a few baths after he shed and there were still some pieces of skin left a while ago. He was also spitting a small amount after I raised the temperatures. A day after I raised the temperatures, he stopped spitting.

There's something covering both nostrils and I don't know if it's skin left from a shed or if it's crust from mucus.

Otherwise he looks healthy, he moves around a lot and can't sit still. He also has a strong grip when I hold onto him.

I've tried getting the blockage off of his nose and I'm wondering what else I can do?
