has anyoned had kratom which caused mouth numbness?

around 10 or so years ago i regularly bought from a vendor whose kratom had a mouth numbing effect. to this day its still the best and strongest kratom i've ever had, by a long shot. even the best kratom i've had since then pales in comparison.

so i was wondering - has anyone else ever gotten mouth numbness from really good kratom? if so, which vendors/strains had this effect?
