After I eat no matter what my stomach tightens up and then my breathing in my chest tightens up for hours. I did the radiation egg stomach emptying test and it shows that my stomach is emptying too slow so not sure what the GI Dr will do at this point until I go back on the 17th of July 2012. I am so lightheaded all the time and it is scary. Not sure if this is related or not. But I will be going to the eye Dr soon to get my eyes checked to see if that is it. If anyone else has ever had anything like this let me know.
