Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Pain under the ribs, release of wind only in sitting position and pains in pelvic area can be due to the following reasons: Colitis or enterocolitis is the commonest cause as it produces wind as well as gives gurgling and so on. Another possibilities are sub-acute intestinal obstruction, diverticulitis and so on. Such a problem can be diagnosed by the following: Get the stool tested and if there is an infection, get a course of an antibiotic, Metronidazole and probiotics which would solve your problem. If this does not help, then you surely need further clinical evaluation by your Doctor or a Gastroenterologist and further investigations like colonoscopy, CT scan and tests of blood. These will give a proper diagnosis to be treated well. If all the tests are negative that is within normal limits, then the possible problem can be IBS that is irritable bowel syndrome. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. T Chandrakant
