Unfortunately, I was well into my 3rd week of my first-time-ever shingles episode, when I found out about the Norasil cream. The rash on my back was pretty much healed, but a new one on my front leg from ankle to knee had began a few days later. I was having excruciating nerve pain from lower back to my knee on left side. I couldn't sleep at night. Upon using the Norasil cream on my leg, I immediately felt some nerve pain relief & no pain (less sensitivity) on the rash. Hopefully I will never get the shingles again, but if I do, I hope to have the Norasil cream handy!
