Never been bitten by a Ball Python, but my most painful bite was definitely the one from a Redtail Boa male. He hit a vein in my hand and the blood pooling under the skin swelled up to golf ball size within a minute!! My hand turned all kinds of colors over the next few days, but that was due to the blood, which also made it painful. The swelling. Felt like a bad bruise.

And I had teeth making their way out of my hand a few days later, LOL. By then it only itched. But yeah, he got me good.

Jungle Carpet bite was also not fun. But nothing like that Redtail.

And the 2 bites from Green Tree Python babies were actually just cute. No pain.
