I agree with the notion that if there is no diagnosis it doesn't exist, as believed by doctors. I'm on this list to learn more about my mother's parkinson, but I had a problem a few years ago which shows this up. I was not digesting food properly in that I was constantly having diarreah (I've never been able to retain the spelling to that word) as well as throwing up on a pretty steady basis. I went for tests and they all came back negative. I ended up with a violent case of throwing up which would not stop and ended up in the hospital. After a week and many tests they still came back negative. The gastroenterologist's response to my illness was, "You're having some problems with digestion and you're overreacting. He repeated this to my primary physician who was incredulous and who gave me some medication for my problem. Two years later I was still overreacting and still taking the pills to help me. It's a little better now, but the problem has still not gone away. The doctors did not know what my problem was, were not interested in pursuing anything that could not be found with normal testing, and therefore, I had no problem. Be careful. Doctors speak to you as if they know the answer. They don't. My father the caregiver, has learned more about Parkinsons from my information that I've received on this list, than from any doctors my mother has seen. Freda Kreiner [log in to unmask]
