I am Chat Doctor answering your query. With your history, it seems that you are suffering from colitis which gives rise to such symptoms. Depending on the area you stay, meiosis should be kept in mind and a course of metronidazole after a routine stool test would relieve you of your problem. Add to it a proton pump inhibitor Chat Doctor.  Consider modifying your dietary habit toward more of roughage, and enough liquids. If it does not give you relief, then you might have to undergo a gastrointestinal endoscopic evaluation by a gastroenterologist. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. Wishing you an early recovery. Chat Doctor. </s>
