My right ear has been swollen ever since I stopped stretching?

I stopped stretching my ears and took out my 0g plugs in January. I remember experiencing problems with my ears once I stretched to 0g such as bleeding, swelling, crust, and pain. So I decided to take out my plugs and return to normal ear piercing size. My left ear has healed perfectly fine and I could wear hoops and heavy earrings but my right ear is still swelling to this very day and it hurts when I wear heavy earrings. I left a stud in my right ear for about a week and started cleaning it with a q tip dipped in alcohol but it doesn't seem to be helping. It also seems to be secreting discharge from the hole. Any tips on healing? I tried going to the doctor but it didn't really help.
