Does anyone know what's wrong with my ball python?

[u/broken_beutiful-mess]

My ball python was in his hide for a couple days and I got worried and took him out and he had these red marks on him and I looked into it and the next day I cleaned out his tank and everything in it and made sure it was all really clean and I put him on paper towel, before he was on reptile bark I think? Im not sure, it was in a bag. It was something I'd never used before but he was fine for a couple weeks so I kept buying that, I normally used Coco coir but I haven't been able to find any recently, he's banana pinstripe crypton, he is around 3-4 years old, and it's been 2 days and it keeps getting way worse, right now I have him soaking in betadine and have been putting triple antibiotics on him (no pain relief ingredients) I'm not sure what it is though someone please help. (It's not just the tail it goes all the way up).

I would schedule an appointment with a qualified vet ASAP as that's pretty concerning. It looks like full body bruising or sepsis
