I'm not really sure about this. I have a very active bp and his husbandry is fine. Temps 85-89, humidity from 50-65 usually. 2 hides that it loves and spend all day sleeping in. He spends a lot of time moving and exploring and is very curious. He doesn't quite have the head thing that OP was talking about but he is very active. Unless he had some internal problems he is fine.
That being said I bought him from a pet store so that could be just a thing?
