[|Human|] Hi, I have a constant pain in my lower abdomen and back. It seems to get worse with eating; it has lasted close to 46 hours now. The pain is minimal in the morning but seems to increase throughout the day. I am in more pain while sitting than standing. I have had a similar pain before but this is the first time it has lasted over 36 hours. Any idea what this could be, thanks!
[|AI|]  Hi, There sounds to be substantial amount of intra-abdominal pathology which is giving such prolong pain episodes as inflammation in form of diverticulitis, narrowing of lumen by some sort of stricture (as typically the symptoms arise after food intake) or others. Thorough case evaluation with history, physical findings and radiology in terms of CT abdomen with or without copy will help great to reach at a particular emphasis. Hope I have answered your query. Let me know if I can assist you further.
