The most common cause of vague right lower abdominal pain after abdominal surgery is intra-abdominal adhesions, which inevitably cause damage to the abdominal wall, and when the abdominal wall is damaged it may become adherent to other parts of the abdomen.
If the pain is not simply vague in the lower right abdomen, but is also associated with nausea, vomiting, diarrhoea, constipation or flatulence, the pain may be due to other causes, such as intestinal adhesions, intestinal obstruction or enteritis, and may require appropriate treatment.
In summary, patients who experience vague pain in the right lower abdomen after surgery are advised to visit the hospital promptly for appropriate investigations to clarify the diagnosis.
