Hi. Thanks for your query. Noted the history and understood your concerns. Swelling of the anal canal and rectum is suggestive of the following: Prolapsed piles or hemorrhoids. Actual ano-rectal prolapse. This can be diagnosed by the following: Get a per-rectal digital examination to rule out any mass or cancer. Ano-proctoscopy helps further. Colonoscopy is a must in such a case to rule out any proximal problem. Since you have constipation, that is one of the most important reasons for such problems, this has to be treated very properly to have daily soft stool without any sort of straining or so. Since Cremaffin is helping you, you can try Cremaffin plus which has sodium picosulfate too. Take sitz bath in a tub with warm water before and after passing stools. Identify all the foods and beverages that ca cause constipation and stop these altogether. Once the proper diagnosis is done and the medical management fails to give complete relief, it is better to go for corrective surgery or as may be advised by your Doctors.
