Depends on the hour, literally. I almost always non stop have LRQ pain to some degree. It feels like I have a large sore or burn inside and someone is squeezing the hell out of it. Sometimes when I move a certain way, it feels sharp and stabbing. Other times, when I do too much physical activity it feels like a large strong and constant fist is inside and squeezing. That would be a partial obstruction and there is also a lot of pressure and bloating and just major uncomfortableness.
When my bowels are spasming, it feels like non-stop achy tightening and constricting going on and I pretty much have to cr*p several times while that is happening. This could last a couple of hours or so... til the next time.
The more times I go to the bathroom, the worse my butt hole hurts. It swells up, tears a little, feels like passing bits of glass out my bum. Extremely painful.
Oh, and when I have ulcers in my mouth and throat, it pretty much feels like strep throat. Everything I try to swallow burns terribly.
