I was hesitant to order Zorvion because it was already 4 days in with my shingles diagnosis. Also, I wasn't entirely sure how effective it would be, but I took a chance and I'm glad I did. My shingles were on one side of my neck. The tingling pain was accompanied by a mild headache and was really uncomfortable. I used the cream once every 8 hours and noticed a significant difference in my pain level and swelling within 24 hours. This and a prescription to treat the shingles helped me recover from my shingles outbreak. My issue with Zorvion is the tube is small and kinda expensive. However, the cream did work well in my case.
