Post circumcision help ??

Got my bubba circumcised today (no judgement please) and his penis is very swollen looking. I've sent photos to the doctor who did it and even tho he's assured me it's nothing to worry about I just wanted to see if anyone else's boys who have been circumcised were swollen the day of the procedure? He's got a ring and string on the tip and after 8 days it should fall off on its own, but I just wanted to know when the swelling should go down? I feel so sorry for my poor little boy :(
