Should You Shower Before Waxing Do I Take A Shower Before Or After Waxing?

Do i take a shower before or after waxing? - should you shower before waxing

So I read somewhere that it should have some sort of Painkiller, before 2 hours? Advil, Tylenol

And someone has some good advice about this or anything I should avoid or not (their wax microwavavle)
