I have low back pain and rectal pressure/pain when I'm flaring, even though my UC is just on the left side. I attribute it to the inflammation. The colon swells and pulls on the membranes that anchor it in place, and I think this is what causes the back pain. Back pain is one of my first warnings that I need to mend my ways because I may be starting to have a flare. The rectal pain I think is just from the inflammation. That's the first place to flare and the last place to heal. If you aren't using any rectal meds, you may want to ask your doctor about
mesalamine enemas to help with the rectal inflammation.
My physical therapist showed me how to relieve the back pain, so you might consider asking your doc for a PT order for evaluation.
Good luck with your C-scope, and I hope you feel better soon.
Moderate to severe left-sided UC diagnosed 2001.
Current meds are Colazal, Azathioprine and Remicade. Completely off steroids for more than a year now! In remission since April, 2006. Remicade has been my wonder drug.
Now tapering Azathioprine, please pray for me.
