Ok, Hi @Randy McMurder are you saying that quitting smoking causes shingles? I definitely disagree with you! I had shingles March 18, 2018 and I was a full smoker back then!! Pack a day!! Quitting smoking DOES NOT CAUSE SHINGLES!!! Quitting smoking may cause ppl to be very upset, very on edge, and have mental issues, as it's really difficult to quit, but it DOES NOT cause shingles!! The Shingles is caused when the varicella-zoster virus (VZV) reactivates in the body after a person has had chickenpox. The VZV is the same virus that causes chickenpox. So, if you had Chickenpox as a kid, the virus lays dormant in your body for decades, and when you get older it manifests and can become Shingles!! So please DO NOT spread misinformation!!! And, I know many people who never smoked that has gotten shingles. My advice to you since Shingles can come back even after you got it once, twice or many other times, go and get the Shingrix vaccine. It's a 2 part vaccine. Speak with your doctor! So, I am not going to argue with you, but I know what I know about this virus!! And, I am sure my friends on this forum will believe me!
