Every time i wake up in the morning to have to urinate/defacate, my intestines/lower abdomen are in sharp pain. especially, after i go. what's wrong?

Have to Go in AM: You might read==> http://www.Healthhype.Com/morning-diarrhea-daily-chronic-causes-and-treatment.Html for some insight. Morning defection itself is not abnormal, but the pain may well be a red flag to some underlying pathology such as ibs or ibd, especially if these symptoms are new to you. I would make an appointment with a gastroenterologist to have a thorough evaluation.
