Since past 3 months have got alternate constipation and diarrhea prob n along with it bad abdominal pain. After consulting doctor motions are fine since past 10 to 12 days but the pain is still same no change at all. Have got almost all the reports done but nothing is seen in reports. Even CT scan seems normal. Blood reports are fine as well stool test look normal. But abdominal pain is not reducing at all. What could be the possible cause for this. Do I need to get any further investigation done. I also have lot of weekness, restlessness and sleepless nights. Can someone suggest me something.
