I got my cartilage piercing back 4 and a half months and my ear started swelling and my doctor told me that my earing I had in was too short and that I needed to find a longer one, so I started looking and found some but it turned out that they were too thick,and a lady at a store 2days ago told me that I needed to let it close and go to a body piercing place because they had the appropriate needles for the piercing I want. But I just need to know how long until this hole in my ear close?
