You're right except that my "moderate" case got out of hand recently and landed me in the hospital for a few days. I've seen a gastroenterologist. It seems that I aggravate something when I'm on the road bike and I want to work at alleviating that. I've gone months with no issues and then I will go on a road ride and I experience lower left area pain and it's either during the ride or soon after that it occurs. I want to try adjusting my riding position to see if that works......
