Cartilage piercing help!!?

ok. so last summer i got my cartilage pierced at a professional piercing and tattoo salon. The guy used a needle and it was very sterile, and i have a hypoallergenic earring in. About a month ago a bump formed at the top of the piercing and its really soft and squishy, and it hurts whenever i lay on that side when i sleep, or even when it gets slightly touched with anything. I highly doubt its a keloid because its not huge and it isn't filled with blood either, its just regular skin color. how do i get rid of it?! please please help..but i really would prefer not to take the piercing out, i dont want to re-pierce it. thanks in advance [:
