I won't call my self an experienced keeper(just 5yrs) but I've been bitten by quite a few snakes. A bite from an adult Blood Python hurts for about a week, not so much the injuries from the teeth but from the power in the strike itself. I had a bruise on my forearm for a week. Other than that I think anything pass 6 feet will hurt, anything less it's just the shock not the pain. Just my opinion.
