Thursday I took all my piercings out for about 6 hours,I washed my hands and put them all back in. yesterday one started hurting,woke up today with crust on the outside and when I look inside my mouth theirs white discharge from the piercing. it hurts and feels like theres a lump there... I've had my snake bites for 6 plus years and only 1 is like this... heellpppp
