This is going to sound weird, but I have been suffering from SEVERE anxiety issues since last summer, severe abdominal pain, shakes, etc. I have had echocardiogram, nuclear stress test, tons of ekg's and ecg's, cat scan of chest and stomach, tons of blood and enzyme tests, everthing other than slight right side heart enlargement, is fine. I was diagnosed with benign PVC's last summer by my cardiologist after wearing a king of hearts monitor.
