belly button and port pain

i am 9 days post op, doing much better with the gas, but over the last 2 or 3 days i have been having increased pain at my belly button surgical site that extends up to my port site. i had the microsurgery so they inserted everything at the belly button and drug it into place. my surgical site is healing quite nicely. no signs of infection. however i can feel a painful bump just above my belly button and i am still considerable swollen and tender all the way up to my port. plus, the other day the port, or the band seemed to be rubbing on my ribs. i also have a pain that radiates to my back on the left side. anyone else experience anything like this?
