Never had that problem, but if its a pvc or two, i wouldn't worry about it. I was told unless you are having 10,000 pvcs in a 24 hour period, its almost always nothing to be concerned with.
On another note, dont be embarrassed, that made me laugh. Try going over to the Prostate Cancer section of this forum, which is where i spend most of my time. When you see what we discuss sometimes, you will not be embarrased any more. LOL
