cold sores
"I'm recent years...maybe once every 6 months (during times of extreme stress) I will get a cold sore usually on my chin. It would normally take 2 full weeks to heal, was the size of a quarter. I tried everything and my Dr. prescribed me this. It's a miracle...plain in simple. It zaps that cold sore in 3 days and immediately starts healing. You will pay through the nose if you don't have insurance but thank God I do as it's literally $500   for a small tube. My co pay is still $30 but it's worth every cent!"
