3 weeks post op Gallbladder.Still in pain feels like a grape

I saw the surgeon last week. Was told all was fine. I cannot do any bending or lifting with out severe pain and increasing swelling. I always feel like I have a grape fruit under my right rib cage that swells up with movement. I also feel like I have broken ribs. Also my Dr. failed to tell me when I can resume lifting more than 20 pounds. Any Ideas?? Thank You!!
