Hi guys! So my ball python just shed and I was cleaning her enclosure after she pooed and when I got her out I felt a tiny bump on her "spine" as I was holding her. it is really small and you can't see it you have to feel it really. Pictures wont help even if I could send them. It feels hard not squishy and it is really small but it is definitely there. I am worried this is something under the skin I should worry about. I don't know what it could be since it is hard but I just don't want it to get bigger and be a problem later. Please let me know your thoughts and if this is at all normal. I tend to overreact and freak out so I wanted to get more expert opinions. Thanks all!
(It is about 4 inches behind her head on her spine)
