Will my python ever recover?

[nikkubus]

Also, change (improvement) can be very slow in snakes- like "watching paint dry".

It's really important to remember just how much slower their metabolisms are from ours and how slowly they recover compared to us. Even in humans it can take months for bacteria to fully recover after heavy antibiotic usage, and food goes fully through our systems in a day or two. I'd say it's worth another shot, especially if nothing else is working.
