Hello! Thanks for putting your query in HCM. I am a Gastroenterologist (DM). Intestinal obstruction usually causes acute abdominal pain, distension of the abdomen, obstipation (means neither passage of stool nor flatus), and vomiting. But you haven t mentioned any of these symptoms. You simply have constipation and that was somewhat relieved with movicol also. So I don t think you are having intestinal obstruction and still to confirm it get a xray abdomen in standing position to see for any air fluid levels. See for the common and treatable cause of constipation by simply getting blood tests for thyroid profile and serum calcium levels. Take macrogol sachet and some laxative like combination of milk of magnesia, liquid paraffin and sodium picosulphate like Syrup cremaffin plus. If still not relieved consult a Gastroenterologist who may advise you a colonoscopy examination I hope I have answered your query and this will help you. Remain in touch and get-well soon
