I have been suffering for seven months with stomach pain, spasming, nausea, and neck pain. Went through a variety of tests and thanks to my primary doctor, had an upper GI which showed very slow transit of food from my stomach. My gastro specialist could care less and said I had IBS - even though I showed none of the obvious symptoms. I have tried Reglan to speed up stomach contractions but could not handle the side effects. I don't know what to do besides find another specialist. Have no idea what's up with the increased neck pain when stomach problems are at their worst. I do have a herniated disk in my neck. Do you think the vagus nerve is being stimulated or damaged. They also found I have GERD, a common side effect of gastroparesis. Thank you for your help!
