Lingering Discomfort from Gallstone Surgery

I had my gallbladder removed end of Nov 08, by laparoscopy. 14 weeks later, my right ribcage still aches if I sit too long or work too hard, and the most disturbing part is that other abdominal muscles tend to "sprain" easily, maybe even tear. I had a golfball size swelling on the left side below my ribcage after skiing (I didn't fall or do anything involving strain). I asked my surgeon, and she said "Couldn't be related to surgery -- you've had enough time to heal." I think it is related. I've never had abdominal muscle problems of any kind ever. I would like to hear some comments from others...did you have discomfort past six weeks (14 weeks in my case), and eventually, did it go away? How do you gauge how much exercise you SHOULD do when muscles keep spraining or tearing? I'm a little surprised and concerned.
