Please don't interpret my statement as "they're normal" - they are still indicative of a problem. It's just that this is an early warning in high humidity environments.
Too much moisture is a common cause; though it can be as simple as the snake pressing up against something for an extended time (esp with water, or moist substrate involved). I had an amazon tree boa develop blisters after he chose to use his water bowl as a hide. He seemed comfy, so I just put another bowl in with fresh water. (The first bowl was mostly empty, it had gotten spilled during feeding; and he went in after). When I finally forced him out of it, he had a bunch of blisters along one side. Basically, some substrate had gotten pressed between him and the side, which caused the ulcerations. It was ugly, but he was good as new after his next shed. Just took some time and effort...I didn't even get bitten, lol.
