I am informing my gastroenterologist group of doctors on what I am doing, and how well I am doing. These happen to be the same doctors who recommended flagyl and cypro which gave me nerve damage and tendon damage.
I am a retired university professor, and I was the first stomal nurse in my Province trained at Harrisburg Hospital in the USA graduated top of the class.
So you see I have medical training, and have discovered a safe therapy for curing pouchitis without the use of dangerous drugs. I choose to share my discovery on this web site only to help others - including you!
