xmdmom,
My inflammation has been historically lower left sided. The diagnosis was UC for quite some time. However, then the dignosis changed to Crohn's once they saw the inflammation spread a little higher and run a little deeper in the tissue. I would think you have a good shot of it helping. Especially when administered through a colonoscopy procedure and adding the use of LDN. I had it administered through a colonoscopy and endoscopy. So it pretty much lined my entire intestines with good bacteria.
For me it made a lot of sense. The doctor had me on 2-3 weeks of potent antibiotics to kill all the bad bacteria (of course some good was lost as well). But immediately after the course of antibiotics the good bacteria was administered through the procedures to help recolonize my entire intestines. Out with the bad in with the good.
