well i just used a screwdriver to pierce my tounge like 5 days ago there is no puss no color difference exept exactly around the ball because i don't want to irritate it whith a tooth brush so do you think it could be infected? i'm not exactly sure it is swallen but i knew that was going to happen i mean duh it's supposed to! lol well i have word of advice if you pierce your own tounge go from the bottom up because it doesn't hurt as much as going through the top i mean yeah i did it both ways and found through the bottom to hurt less
For the record the don't go through the bottom to top because it hurts less, they do this to ensure they won't hit your vein.
