Lumpy back

I was adopted an adult male bp yesterday and he has one lump midway down his body and i was wondering what it was, he doesnt seem to be in any pain and moves just fine.

Sometimes ball pythons get kinks in their spines... they usually don't cause trouble, but can happen from mishandling and whatnot.

OH ok, thanks, just making sure it wasnt that big of a deal.

Is it a firm lump, a spinal deformity or perhaps just a too large, undigested meal bulge? Where'd you adopt the snake from?

I have seen Both Spinal deformities and Spinal Calcium Growths. on Ball Pythons. The Spinal Kinks are usually something that they have from birth not something they get from weing whacked... or stuck in a drawer, However that is possible although it would proably result in the lower body being paralized.
If its a kink the animal will most likely be just fine as it probably again has had it from Birth. Please however do not ever breed it as it could be genetic.
If the "bump" is not just a uniform raided bump like a kink.. But more like a bunch of rocks on the spine, That is more likely a calcium growth and should be looked at by a qualified vet to see if it is growing and needs to be removed.

its more of a solid bump than a rocky one and the lower half is definatley not paralyzed cause he likes to coil pretty tught around my arm with his lower half. I adopted him on saturday from forgotten friends reptile rescue in lancaster county, pennsylvania. He has 2 more adult bps if anybodys interested, they were in good shape and looked to be a good size and mine had an awesome feeding response the next day i got him. He is also very well tempered and very good around the kids.
