Hi Everyone, I am new to this forum, and have been reading all the threads and thought I would put my thoughts down on why these PVC's come and go for all of us! I believe its the Vegus nerve, in my situation if I have the diareaha, I get them, I feel its because the nerve gets inflamed and there by causing the pvcs. I have thought this for some time, I was free from them for almost 1 year, and had a couple weeks of diareaha, and boom they came back, I am now taking Gasx, and lots of valium (2mg) to stay calm becasue they scare me when they first come back. I am 56 years old, and have had them since the birth of my baby 30 years ago. I to had all the tests known to man.....NORMAL! So try and go about your business, excercise daily, and have a couple drinks in the evening. Hope this helps you all to not worry so much.
