First, if a vet says that your BP is possibly septic, then you need need get that confirmed and/or treated asap. I don't see how there can be nothing wrong with your BP. You've described a bunch of symptoms that individually would be worrisome. Taken together, they require immediate action. The regurgitation and the frequent shedding are particularly concerning.
Secondly, I'd like to help you get your BP's set up dialed in. A properly set up enclosure will help your BP heal and prevent future issues. So, what type of enclosure are you using (PVC, wood, glass)(screen top, front opening)? How big is it? What are you using to heat the enclosure? What thermostats do you use? What are the temperature (low to basking) and humidity ranges like in your enclosure, now? How are you measuring them? What type of bedding do you use? How often do you change it? Don't worry if you don't know the answers to all these questions. Just answer them the best that you can. Pics would help a lot. This thread will show you how to post them:https://ball-pythons.net/forums/show...-Post-Pictures.
I want to finish by saying that I admire the diligence you've shown in addressing these issues. It speaks of someone that really cares. Good luck.
