Thank you for your query. Would you please clarify a few things for me? 1) Was the gall bladder removed laparoscopically (key hole or minimally invasive surgery ) or by open surgery? 2) have you has any other surgeries in the abdominal area? 3)What triggers the sensation? (bowel movement, urination, sitting or standing) 4) how intense is the pain when you apply pressure ( on a scale of 1-10; 1 being the least and 10 - excruciating)? You are already on the right track by monitoring for pain, fever and vomiting. Adhesions ( sticking together of the abdominal structures ) is a common occurence after surgery ( more so after repeated surgeries). When the internal organs, the peritoneum ( sac that covers most of the abdominal organs) and adjacent structures are exposed to foreign objects (like those during a surgery) inflammation occurs which alters the surfaces resulting in adhesions. these may or may not cause pain in the long run. Appendicitis usually presents as pain in the periumbilical region which migrates and localizes to the right iliac fossa (just above the area where your leg meets the abdomen) and is associated with fever , vomiting and tenderness in most cases. Unusual location of an appendix (near the liver, for instance) can present differently. Based on your query, adhesions seem more likely. I recommend seeing your physician who could quickly examine you and try some maneuvers to elicit an expected response which can help to rule out other pathology. Adhesions are managed conservatively (pain and antiinflammatory medications, if severe) or surgically (debilitating pain- ironically surgery can cause further adhesion after a period of time). Hope I ve helped. Please feel free to get back to us should you need further clarification. Wish you good health
