Strange UC Symptoms: blood, but solid stool 1x day. Anyone else have this?

Some background: was diagnosed with pancolitis in 2010. Asacol worked great until a really bad flare up in summer 2014 (6-10 BM/day, usually just liquid or mucus, usually bloody). Struggled for months to get it under control, finally managed to get it in december with a combination of asacol (4800 mg/day), Uceris (1 tablet/day), 50mg oral pred, a month of predfoam, and going on the SCD diet. I've been off the oral and rectal pred for a few months now, tapered the oral stuff very slowly. I've consistently only been having 1-2 BM per day, no urgency, very solid (even feeling almost constipated sometimes).

The weird part is I'll still get occasional blood. This blood isn't mixed in with the stool; rather, it's dripping into the toilet bowl. Usually what will happen is I'll get some stool out, it'll be normal and there'll be no blood. Then a minute or two later, I'll start dripping blood into the toilet bowl. It's almost like there's a cut somewhere external on the anus, rather than the blood coming from inside the rectum or further up in the large bowel. This only happens every once in a while, I'll go a few weeks without this happening, then I'll have a few days where every other BM or so I'll get this, then it'll go away again for a few weeks.

Anyone else experienced anything like this, or have any idea what's causing it? Or how I can even pinpoint whether it's internal or external?

Thanks. No, I have no history of hemorrhoids. Looking at the Wikipedia page for hemorrhoids, it does sound like an internal hemorrhoid: "Internal hemorrhoids usually present with painless, bright red rectal bleeding during or following a bowel movement. The blood typically covers the stool (a condition known as hematochezia), is on the toilet paper, or drips into the toilet bowl. The stool itself is usually normally coloured." That's exactly what I'm seeing. It also talks about itchiness, which I very occasionally get from time to time.

Is this related to my UC, which seems to be pretty firmly in remission now?

If it persists, your family physician can diagnose hemorrhoids, just expect latex gloves and a finger. It can also be uc bleeding, although your stools are now formed it could be the signs of a uc flare starting. You would need an exam from a doctor to distinguish between those things.
