The pain in stomach is on right side of incision. Back pain radiates mostly to lower right side. The first week lost 13 pounds, second week lost 11 pounds and this week was only one pound but my DR isn’t worried about that one pound. 25 pounds total in three weeks and the stomach and back pain just came on suddenly Friday. My first two weeks post op went great! It’s unbearable. Thank you, everyone for sharing. I’m new to all this and any feed back helps.
