Hello, I have had lower right abdominal pain that will occasionally wake me up through the night. It also is painful to press on the area of pain. I did have my spleen, 75% of my pancreas, and benign tumor on it removed about a year ago. I have been having this pain since they found the tumor. Some people have told me it could be from my ovaries but it doesn t take place a little before, after, or during my period. Do you have any ideas??
