passing red blood either with her stool or just by itself!

Hello and welcome to e health forum.

Blood, mucus in the stool and severe crampy abdominal pain, associated with nausea, are some ‎symptoms that indicate conditions like ulcerative colitis, Crohns disease, Dysentery, hemorrhoids, ‎Ano-rectal tears, etc.

Since the colonoscopy has shown findings of inflammation the most probable cause could be ulcerative colitis. If not done earlier a biopsy of the colon mucosa might be confirmatory.

You might consult a gastroenterologist who might get additional tests and initiate proper treatment for the specific condition.

I hope this helps.‎
