It seems like I have back issues when I have bad stomach cramping. I had an ischemic colon a couple of years ago. My stomach was never the same. Eight months after that I had a severe case of Cdiff. Actually 4 relapses, a trip to the hospital by ambulance, & finally after failing all the meds, I had an FMT. That was a year ago. I still can’t get my bowels & stomach to any kind of normal. I’ll be fairly ok for about 2 weeks & then for no apparent reason I’ll get cramps bad enough to almost cause me too pass out. Then the next day my muscles in my thighs feel like I’ve run a mile. Absolutely my back is like I’ve hurt it. Has anyone else suffered with this maybe after Cdiff ?
