Could be an internal hemorrhoid. I've had them recurrently lately, they bleed and sometimes hurt a lot, and they make me feel like I'm not empty - like there's still "stuff" in my rectum that I can't get out, but it's just the hemmie. Depending on where they're located, they could probably cause drainage or incontinence too although I haven't experienced those symptoms myself. For what it's worth, I also seem to be in remission and my fecal cal is also in the normal range.
It is something you should get checked out to be sure, though. If it's a hemorrhoid, your primary care doctor or GI should be able to find it either with a finger up the backside or an anuscopy - neither option is particularly pleasant, but it would be good for you to know for sure what's going on. I treat my internal hemmies with steroid suppositories and that's been working pretty well for me. So call your doctor and get it checked out.
