I'm 49 white male with history of hypertension. I have been having some weird symptoms lately. I develop nausea diaphoresis, elevated blood pressure, lose stools. I have had many episodes for the pass few months. I have gone to the hospital but they cannot find anything worry some they send me back home telling me that everything is okay. I take coreg, hctz, amlodipide, simvastatin, I have missed several days of work because I fell miserable. I was just wondering if this not cardiac related what could it be? Thank you
