I had my fissurectomy 10 days ago and i was put on lactulose (a table spoon every 8 hours), i followed the regimen for 5 days but now i get severe bowel movements that i feel like exploding when moving and sometimes stool would push out of me against my will with severe pain, i want to go to the toilet like every 15 min. Is it from the operation or the lactulose? what if i take a purgative will it stop this agony. the stool comes out with effort so near to labor pain, though they are very small simulating a tear drop!!!
