I think a lot of people have sacroiliac pain, period. There is an increased association of lower back pain with UC, and sometimes that is because of ankylosing spondylitis, but usually it is not.
Perhaps people with UC are more susceptible to lower back issues because we are less active? Too much straining at the toilet? I don't think anyone has the answer.
I've had SI pain for most of my adult life, and after a LOT of investigations and studies the main conclusion is that I have arthritic changes at L5/S1 (the most common place of spinal osteoarthritis) which apparently causes a mechanical dysfunction in my pelvis. I also think I have stretchy ligaments - my SI joints are usually out of whack. In my 20s I learned some stretches to get them back into the right position.
Here is my best advice:
1. ABSOLUTELY GET PHYSICAL THERAPY. At the least, you will learn how to self treat SI pain. At best, you will feel a lot better.
2. KEEP YOUR CORE STRONG. REALLY STRONG.
3. KEEP YOUR HAMSTRINGS, CALVES and HIP FLEXORS flexible. This means stretching. Often.
4. LEARN HOW TO SIT PROPERLY in your car and at your desk. Get an ergonomic evaluation at work if this is available to you.
5. KEEP YOUR FEET HEALTHY. There's a really strong connection between bunions and lower back pain. Seriously.
