Hello doctors, I have done my endoscopy. Ultrasound and CT scan everything is normal. I have had this pain on my lower left abdomen and sometimes the whole of abdomen only after a bowel movement. After the bowel movement I also feel like I have diarrhea. Not sure what is wrong considering my contrast CT scan shows no abnormalities. All other organs are normal. Any idea what this could indicate. It's been going on for more than a month now.
