What causes abdominal pain?
Patient: I am a 42 year old healthy female and  have experienced a  severe sustained increasing pain in my upper right side abdomen in the past few days, I shift positions and that helps but the pain does not seem to go away. I was hoping it was gas or diet related so I kicked up fiber intake to flush my system and notice black pellets in my stool today with  no blood present and I am in less pain at the moment, what does that mean ? Doctor: Hello! Welcome to HCM.Right upper abdominal pain suggests gall bladder related pain.As you said black pellets, there can be occult blood positive if you do stool exam for it.This can be due to bleeding somewhere in upper gastrointestinal tract.This can also be due a stone in ureter causing obstruction to urine outflow.In my clinic, many such patients do come to whom I advise ultrasound abdomen & pelvis, urine & stool routine, CBC.Treatment is done accordingly.Hope this information is useful to you.Wish you speedy recovery.Thanks. Regards.
