<s>[INST] On Sunday night I noticed this really sharp localized pain that would occur when I coughed on the lower right side of my abdomen right south of my navel. The pain itself doesnt feel gastric, instead it feels like the muscle is strained or like there is a bruise in the area. At first the pain only occurred when would cough, but now sudden movements hurt too, and the pain is from my lower abdomen up to the the bottom rib on my rib cage and feels like I have a big bruise in the area. The pain has been lurching to the right and the area is tender to the touch, but it is also fairly mild. I dont have any more symptoms; no fever, no loss of appetite, no nausea, and I really havent engaged in any activities to bring this on. I was just wondering if I should be concerned about this due to its sudden nature and the area of pain. [/INST] Hi. Thanks for your query. Read the history and understood your problem. Pain in right lower abdomen on coughing and now even moving but without any obvious other symptoms of fever, nausea or appetite problems. In such a situation the best way is to do the following:Get examined by a General Surgeon for clinical evaluation and physical examination as in these cases the physical examination by an expert can clinch a diagnosis. The investigations may help to rule out certain conditions. Get CT scan of the abdomen and routine blood, urine and stool tests, Colonoscopy if required. </s>
