Stress.... that's what the doctor said... just that week was one from hell for me, not going into details, suffice to say I have had enough occurences that it has prompted me to scale back on a few things! Never had a barium done before, I am hoping the new pills I am on stop this from happening again. Told the ER nurse I felt like a complete idiot showing up in ER with this problem, she told me you don't know if it's yer stomach or yer heart do you? We have the tools to rule either out. It has been drilled into my head you go to ER only if you have a knife sticking outta yer skull etc. Well you get the picture.
