alternative_health_for_me,
Yes, I hadn't had any problems for many years but I had chicken pox when I was a child. My Dr. says that herpes zoster is in your system after the chicken pox so it can remain dormant for years or for ever but there is something in your system that can trigger it if its there.
My trigger is high anxiety and stress. Check into the shot, it's supposed to diminish the itching and burning if not eliminate it.
Your diet seems healthy but you should check with your doctorf since it's possible that you're missing something essential for your body. However, if your diet has been this for many years, it may be that instead there is something in your life that has changed, even gradually over this past while that has accumulated and is causing you stress, even unconsciously, that causes the effect of shingles.
I applaud your preference to alternative medicine as I too believe that long ago humans didn't have any doctors with synthetic medicines to fix every little thing so look to yourself to see if anything has changed in your life or anything different in your diet, such as a different brand of vitamins, or even a different brand of laundry soap.
I remember many years ago my mother switched from one laundry detergent to another and my sister and I were sent home from school because the itching became so bad.
Good luck and let me know if you find out what the problem is. I hope it is something as simple as a different brand that's composition is enough for your body to react.
