How to get the swelling to go down?

Karla

My 2 and a half months old tragus is still swollen and it got so swollen my jewelry is now too small! (I had it downsized two weeks ago, but I guess the tragus grew again and now my stud is pushing into my skin and I have a bump on the inside of my ear)

Is there anything I can do to get the swelling down?? I do salt water soaks twice a day and spay some antiseptic spray which my piercer said I could use...
