Had the same problem before and had to take out piercing, it was pus and gross. It’s about 4 weeks since i got my ears pierced and a lump/little mound behind my ear next to back of the ear piercing, it’s not painful but the ear is and it’s not crusty only skin coloured so it’s not red or anything, it was soft before but it’s hardened, i really don’t wanna take out the piercing. What should i do?
