Do bumble bees leave their stingers?

Yes it does have a stinger but it does not lose it when it stings you. It is a hornet and since it doesn't lose its stinger when it stings you it can sting you over and over again. I have ran over a hornet nest entrance and they attacked with full force and didn't let up until a minute or so later. I ran flinging my arms and smacking them but it didn't do much of anything at all and it hurts for hours unlike wasps that don't lose their stingers either.
