Weird bump

[Bogertophis]

Update: They already injected her with an antibiotic called ceftazidime.
I think I trust this vet, he seems to know a lot. He has multiple degrees surrounding herpetology and treated many reptiles, He was also president of a reptile group that I forgot the name of. He took a tissue sample today and sent it to a lab, I'll get results in a week.

His guess was an abscess or a cancer. He did an X-ray and her heart was normal, the growth/abscess is in front of her heart.

Because of where it is located, he won't do any surgeries if it is a tumor, I'm hoping it's just an abscess. He didn't drain it, so I assume it's still in the early stages? I'm going to the vet every 3 days for an antibiotic injection. Should I start the probiotics now? Or after the antibiotic treatment?

Thank you all for your help, I'm so happy I'm apart of this community. ❤️

As Armiyana said, this extra info changes everything- Yes, listen to this vet! Also Never give probiotics to any animal (or person) while they're on any kind of antibiotic.

Probiotics are only appropriate AFTER all antibiotics are completed, as this vet will surely tell you. I would also ask your vet after you complete antibiotic therapy on this snake to make sure your vet is satisfied that no other antibiotics are needed.

We're glad you're here too- And we're all hoping the best for your beautiful snake.
