I too had a flipped port. I had no pain, therefore no clue. At my second fill appt. my Dr. couldn't manage to get the needle in. I could actually hear the needle scrapping the titanium on the back of the port. He scheduled me immediately for surgery. I was under general anesthetic. It really wasn't so bad. The worst part of it all was the set back. I was banded in Sept.08. I then had a small skin infection near an incision and could not get a fill until it cleared up. In Jan.09 I had the port correction surgery and all the fluid taken from my band. I had to wait 6 more wks to get another fill. Essentially, I had to start over but I am down 28lbs. I am finally starting to feel this has been worth it. Still, I can't help but feel frustrated when I read about people who've had their surgery around the same time and lost 50+ lbs.
