Well dearies,
i too, have been having this problem since 2003, and let me tell you something. You need to get a barium-burger test done to see if you have a twisted stomach.
Dr. William chey, in rochester, ny might be able to help you find a solution (my solution? Don't eat any fat, keep it out of your body, forever. . .) keeping away from fat is hard for me because I am a reformed junk food junkie. However, I had an operation for malrotation of the stomach. Feeding tube placed in my abdomen, that I would have to turn three times a day: all to prohibit my stomach from twisting into a knot. Well, for the most part, it worked, however, I also have gerd, and need to watch everything I eat, because even the slighest wrong taste in my mouth will completely repulse me into a vomiting frenzy. Joy! >:{
so, we fix gerd with protonix, and we fix stomach, but I am still in miserable pain/taking vicodin to quell that rain.
One other thing you might want to check on (which I suffered from) is h. Pylori. A bacteria in the stomach which basically eats away the lining of the stomach. Rather brutal amount of antibiotics, but got rid of that as well.
So, what am I trying to say? I'm in this shitty thing with you, and I am working on many different theories to help myself and others feel better.
We still don't know why i'm in so much pain, and why i'm still vomiting every day, but I know I will find ways to better myself, and focus on my artwork and music.
Try yoga, pilates, and very gentle exercises to help tighten your insides. It's a pain in the ass at first, but when you start seeing the benefits, you don't want to stop.
Good luck to you, and please, check those two symptom related diseases. Might make some sense out of the matter.
Sweetly yours,
suzi willpower
