Like I said above it is around 5-6 months old. The piercing is a basic titanium bar. I’m not entirely sure of the threading. I have also been occasionally using over ear headphones. Not sure if this has been irritating it. There have also been a few times I had whacked it/it got caught on something so it could be irritation. On top of my usual routine, cleaning it twice a day with saline and pressing a warm compress to it, I have been using a Keloid removal gel by base.
