I just bought a Ball Python. He is about 2 1/2 years old. I checked him over when I was at the previous owners house. I guess I didn't do a good job. When I got him home and sat down with him and really took my time looking at him I noticed a couple things. He has a big sore that is redish with a little yellow tint to it. I have never seen this before. I have checked him for mites and ticks and has none. What would this sore be from. It is located under his belly about the middle of him. He also has a couple bumbs that are on his sides that are kinda like a pimple under his skin trying to make there way out. Hard, and dry bump with a little dis-color to them. What would this be? If anyone could help me with these questions please do so. Right now I am trying to find a vet to bring him to in my area but not having luck. Thank you for your time, Bonnie
