Isla, TG, thanks for the info on Lysine, one of the doctors had heard something about it, but told me to look it up on the web! Anyway, I don't eat any seeds, nuts, peas, or chocolate. Of the four, seeds are the only things I can even stomach.
FYI, here's a little info I found out at
Dental Zone:
Canker Sores ( Mouth Ulcers ) :
Are strictly intraoral meaning that canker sores occur only within the mouth.
Are not contagious meaning they can not be spread from person to person.
Are not caused by a virus.
Fever Blisters ( Cold Sores ), on the other hand:
Are preceded by small blisters called vesicles.
Usually occur on the outside of the mouth although they sometimes occur on the inside of the mouth. When they do occur on the inside of the mouth, fever blisters appear on bound (non-movable) sections of the mouth such as the mouth roof.
Are contagious meaning they can be spread from person to person.
Are caused by a virus.
My doctor tried Zovirax (herpes treatment) to prevent them, but it didn't do much good.
