OMG Chell
Im so glad to see this brought up 
I had problems for years and one day a friend of my daughters was at my house and we were discussing "things" and she told me of a regime she was on for Candida Albicans  
Well, a friend of mine who was on Atkins with me, told me after i was not losing that she read that people with candida didnt always lose on that diet 
so i began looking into it 
Here is what i found 
There is small info on the web, but it is there, 
Few Doctors will admit there is such a thing 
It is often caused by an over abundance of anti biotics 
Too bad docs dont recognize it because often they treat it with anti biotics  LOL
I found a Kinesiologist to treat me.   Insurance co's dont cover natural medicines and wholistic doctors and i was lucky because of that young lady at my house, that she told me about a local chiropractor who had a reputation for miracles. She was also a kinesiologist and treated me with herbs and (Im sorry cant think of the name of what you call them)  natural products
My diet was very strict as i was found to have candida  mold and a myriad of other related things
If you want i can give you an overview of diet  but caution it really is strict  you can eat very little but i recommend you seeing if you can find a kinesiologist and see at least if he/she can test you 
There are books available in Amazon.com on diet and meal planning 
Gas and pain are not the only symptoms  but as you search it on line you will see lots others 
I lived with a morning headache that sometimes lasted the whole day, i had brain fog at times, which meant i just couldnt concentrate. One day i was lactose intolerant the next day i could have all the dairy i wanted. My body never reacted the same way twice. And I could go on
But    hopefully we dont have to be embarrassed here, the gas was horrid,,, i would not flatulate (fart LOL) once  but sometimes i would just keep coming on and on  and the smell was horrid.   Very embarassing when in social situations. 
feel free to contact me off list if you want
