I've had a "streak" in my stool for about a year, and now have been having bright red blood on stool as well as an anal pain. what's going on? nervous

You need an exam!: The most common causes for blood in stool and anal pain are hemorrhoids or anal fissure and can be treated with medication or rarely surgery. You must see a primary care doctor to confirm this. Other causes are colitis, colon polyps and colon cancer. If you don't have an obvious anal fissure or hemorrhoids, then you must see a GI specialist to make sure you don't have any of these conditions.
