So I have an irrigation bump on my Tragus piercing and so I have been cleaning i over excessively with tea tree oil and saline water. A couple days ago I noticed a hard, almost bone like bump behind that ear but I can only feel it when I turn my head o face fully right and almost stretch it. Other than that I can’t feel the bump. The bump is also not visible to look at is literally only felt under the skin when I face fully to the right. At first I thought is probably due to excessive fluid from the oils and saline going into my ear that probably caused something but because it’s hard and just feels like bone im a bit concerned. What should I do??
