Hi. Thanks for your query. Noted your history of having colonoscopy today and had 2 polyps removed. Since you have arrived home you have developed dull pain in the left lower abdomen, constant and stabbing pain if you move. And the left thigh and groin too is affected by the pain. This can be a trapped wind, but there is a more chance that there is a perforation of the colon. Hence I would advise you the following things to be done immediately. Rush to the ER or the hospital where colonoscopy was performed. Stop taking anything orally. You need an urgent admission, intravenous fluids and intravenous antibiotics too. Investigations: X-ray of the abdomen in the standing position is still very important simple tests that can show the air under the diaphragm as an indication of bowel perforation. If there is a perforation or even a suspicion of perforation, you need an urgent exploration to see the cause and also to get a proper treatment. Timely diagnosis and treatment is very important for saving the life as this can save the life.
