@omnimirage sayed; "If the venom does run out so quickly, then it wouldn't be worth trying to remove it if it takes for example more than half a minute."
The muscles around the sacs can be seen pumping with the naked eye - or at least back when one could - and
that time has never been counted by myself, but from tissue reactive within some body zones I'd say at least
60seconds, maybe as much as 180.
This guy did some work I lean to agreeing with, mainly because of his venom container selection. The pain
levels charted are also pretty close to my own experience.
https://peerj.com/articles/338/"A sting from a honey bee is familiar to many because of its world-wide distribution. The sting can be reliably provoked, and standardized, making it an ideal experimental stimulus."
The point of the exercise I laid out is that there are two stages, the second phase being the crescendo of pain
levels until the venom pumps in whereon swelling occurs, and for many that pain of swelling is greater than
the whole of the initial event, and way more enduring.... days for some folk I have known.
Hence prevention (scraping off) is the path to confidence.
