Lately i have had to push to get a bowel movement started. can forcing cause the colon to get irritated so blood appears on feces? can it be hemmoroid

Hemorrhoids or not?: Bleeding from the rectum that recurs may also indicate anal fissures, proctitis (due to infection, inflammatory bowel disease, radiation therapy, stercoral ulcers, rectal prolapse, trauma, etc.) or a bleeding source further upstream. Depending on your age, risk factors, current medication (aspirin, nsaid's, anticoagulants can cause bleeding), get evaluated sooner than later.
