I've had my lip peirced and I recently got a vertical hood piercing. Both hurt, the genital one far more, but I wanted them there, and the pain was gone in about 3 seconds or less.
Your tongue is supposed to hurt considerably less than both of those piercings, and I'd probably rate the lip as a 4 or 5 and the VCH as maybe a 7. In terms of piercing, not other kinds of pain. Like childbirth would probably rank 20 or 25, I guess.
Healing time for your tongue is about 1 or 2 weeks in terms of eating regular foods again. No oral sex or deep kissing for 3-6 weeks.
