Need help with caring for Rook Piercing?

Munchkins
So I recently got my rook pierced, I think it was about 4 or 5 weeks ago. The piercer said it would be healed in 6 weeks, I'm not sure how true that is because when I look at my piercing it still looks a bit swollen. Nothing hectic, just not the same size as the unpierced rook. Otherwise it's good. No pain, no pus or oozing. How long will it take to reduce the swelling? And what can I do to reduce the swelling?

Thanks for the comments. How often do you recommend I clean it? Once or twice a day?
