Yes, I've had the same problem when I was flaring. My back hurt as much as my guts, but my guts didn't react well to the chiro, except with one very gentle Chirpractor.
Here's what does work, and perfectly as it calms both my back and gut: Bowen Therapy.
It comes out of the Osteopathic tradition and gently realigns the tendons, which get out of place and can cause all the other pain. I used it originally for migraines (I say I'm cured of the, maybe one a year vs 5 a month). The bonus is how it made me feel more balanced over all.
In 2005 I had surgery to reverse an ostomy and had a auto-immune reaction to abdominal mesh, and I would up lying down for nearly 2 years. I am not as young as I once was, and my back and hips had a hard time as I began moving more. Bowen set me straight.
It is supposed to be a finite course of treatment with an end, but I find I go back to help with things as they crop up.
That link is but one Bowen site with a link to practitioner search, as well as this, google Bowen and your country and see if other's come up as not all practitioners register with all sites. Oh the ones with the * have more training. If you can find and ND (Naturopath) who does it, mores the better as they can help you with other things too, and insurance (if you have) may cover it, or it can be a tax deduction.
If your in Canada, let me know where you are, I know people who can help me find some one good for your area.
I have tried most every body work, this by far is the most beneficial! I cannot say enough good about it.
