There is absolutely, 100% NO WAY the
Lidocaine effect lasted 3 weeks. Zero. Zilch. Nada, as they say.
Lidocaine is very short acting...and would be completely out of your system within hours, not weeks. Whether or not it triggered the initial round of PVC's, I can't say, but it DEFINATELY did not make them last 3 weeks. I doubt you will believe me.
PVC's are a very common and annoying problem...seems just about anything and everything can set them off, including anxiety.
