I just got my clitoral hood pierced vertically last week. Within three days a hard lump formed in the skin near the piercing. It actually felt like a ball to the barbell was stuck inside but I checked and that was not the case. Now a new one which is also hard and inside the skin has developed just below the other one. They are tender to the touch and if you look at my clit you can see it is swollen on one side. What could this be?
