i read something recently that constipation leads to hemorrhoids, rectum bleeding and so on. eventually when it gets worse or not treated or if it keep coming again, it could be cancer.
i did cancer marking recently my crp was high. did colonoscopy, d doc couldnt find a thing that might cause d bleeding. its been a week n its still bleeding. i just don know wat it is. its not hemorrhoids, cuts, infection, polyps, cancer, nothing. now they said they wanna cut me n see whats d cause but i find it unnecessary. i was really scared this pass few weeks, but then i realize that ur age do really matter is ur aiming for worse.
get second opinion. and also pain in pelvic and left abdominal area can be bad. could be risky in the future. if u havent done colonoscopy, then u should...
p.s i cant tell u what ur having, i dont have the right to diagnose
hope it helps
