I got my tongue pierced and it got infected. i took it out and, now it's sore. what is the best way to treat this?

See your doctor: Or an ENT for an evaluation of the tongue and leave out the piercing.

Tongue Piercings: Don't know if you are currently on antibiotics or not. If your tongue is seeping drainage that is other then white-colored or that is malodorous – then please seek medical care. Try saltwater gargles. Mix tsp of salt in 8 oz of warm water – gargle w this several times/day.
