37 yr old male 170 lbs. when I lean back, I can see a stomach mass the size of my fist directly center of my abdomen. I went to dr. he sent me for ct scan. doctor says ct scan looks normal. I really dont have any pain or discomfort, just dont know what this could be. Bowel movements are mostly small, sometimes flat, sometimes clay colored, I also have the urge to go several times a day with very little outcome. any advice would be greatly apprecieted.
