Nausea after bowel movement and occasional bleeding but i think that may be a ruptured pile.waiting on colonoscopy for past 5 months.very loose stools?

See a GI doctor: Can't imagine why it takes 5 months for a colonscopy if you are symptomatic with diarrhea and blood in the stool. You must discuss this with the doctor and if they will not schedule you sooner, seek another opinion. Do not assume the blood is from hemorrhoids. If it is, great. If not you need to clearly determine the source. Hemorrhoids will not explain your other symptoms. Get seen and get well.

Go to ER: If you can't get an appt due to restriction or limited availability of specialists in your HMO network, go to the ER before something really bad happens.
