Orange oily leakage from rectum, and pain on lower left side of stomach, close by pelvic. what could be going on? just finished hemmoriod treatment

Sounds like: you should mention this to the Health Care Provider who treated your hemorrhoids!!! This may be residual from the treatment itself! Hope this helps! DR Z

Likely mixed blood: Likely mixed blood from hemorrhoids, but be sure you have seen Gastroenterologist to rule out other inflammatory or infectious causes of blood and hemorrhoids. Happy to consult further on proper hemorrhoid care; will need more info of course.
