I had a sleeve gastrectomy 2 weeks ago and I just started feeling this sharp pain 4 days ago in my abdomen on the right lower quadrant. The pain is nowhere near my incision. It is just lateral to my bellybutton. It feels like I'm being stuck by a knife or pinched really really hard. The pain is the worst when I'm sitting, when I lean up when sitting, or when I bent over to pick something up off the ground. This is excruciating pain. Is this something to worry about?
