PLEASE HELP A GIRL OUT

I got a mid cartilage piercing on Dec 5 of last year. I got it done at piercing pagoda with a gun. I didn’t have any issues other than the typical pain until around March i noticed that a little bump was forming. And with the bump came some pain, but i was able to work the pain down and had no issue. After 2 weeks i noticed more pain and i decided to go to an professional piercing place to have them check it out. I met with the piercer and she told me that bc it was done with a gun and they angled it down my hole was not 100% healed yet. She told me to take some crushed up aspirin paste and leave it on my ear for 30 min and continue to use alcohol to clean it. Then change my earring to a hoop so it can heal, and everything should be fine in a week or so. That was 3 weeks ago and my “little” bump on the back of my piercing has doubled in size and this morning i woke up to a large amount of ear pain. So i go to look in the mirror and in the front of my piercing is this massive red bump. So i cleaned my hands and started checking it out. I touched it a little bit and a large amount of while pus came out. I immediately cleaned my ear but from here i have no idea what to do.

I don’t want to have a massive keloid form on my ear. And I really love this piercing but the issues it has caused me have far out weighted having it . If anyone could offer me some advice about where to go, what to do, or what’s going on i would really appreciate it !
