Sorry if I am posting this in the wrong section, but I got a text from a lady with a ball python with a swollen face(the right side of his face is pretty swollen) and she has asked me to take him in. I really wanna help the little guys out but wondered what all I could do to help him? Heres the picture she sent me


I know a vet trip would probably be in order, but does anyone have any advice I can do to help him before hand?
