About three months ago a patch of zoster appeared on my back.
My entire leg was cramped. I used the zapper for 20 minutes twice that day and the next day the pain was gone.
Then my left foot was covered with herpes. I zapped and used lysine and now control it with 2,000 mgs of C twice a day.
Good to dissolve 1000 mg lysine in little water and rub it on. Burns but dries it out. I also avoid some foods.
It’s a good little zapper.
