hi Lynnwood,
Oh dear, that sounds very uncomfortable. I know that with Fibro, irritable bowel can be an issue. I notice the "urge" much more frequently if my fibro is active. I have nothing but really loose, or the "big D" when that happens.
Did you notice your previous episode with this during a lupus or fibro flare? It's so hard to pinpoint isn't it....
All I know is that taking my daily acidophilus has helped tremendously with my bm's and the gas too. I had a hydrogen breath test done a couple of weeks ago to see if I had any intestinal bacteria issues. The results came back 100% normal. Not a single bit of bacteria in my system. My GI doc said it was from the 3 years of probiotics that I've been taking. He was thrilled and said that very few people who are on acidophilus have gas/diarrhea, cramping issues.
I can't remember if you are on a probiotic already? I recommend it for anyone!!
Hopefully someone else will have more info and ideas for you.
Ginny
