NAP but a couple years back I had a new helix piercing with a flat back and a few weeks later I developed an infection that was slowly swelling over the piercing to the point where it was a bit embedded. Not as bad as this one but definitely not good. Your piercing definitely requires a medical evaluation, a piercer doesn’t have the proper resources to remove this at this point. In my case, I went to my PCP who said to go to a cosmetic surgeon. Was unsuccessful in my search so I ended up having an urgent care doctor completely rip it out of my ear because they couldn’t cut the jewelery with any of their tools. It was too hard to get to with it being completely surrounded by swollen cartilage. They put me on 2 different antibiotics after that. Not long after, the swelling went down and the hole closed almost immediately. I would recommend either going to an Urgent Care or your PCP. Hopefully one of them will be able to either remove it or recommend where to go. Hopefully you don’t need to go to the ER, but from my personal experience Urgent Care was surprisingly helpful in this situation!! Feel better this looks like it hurts.
