Absolutely one can have canker sores....not herpes.....but my point is to make sure what it is.
Canker sores can be caused by lowered imune system, stress, certain foods, autoimmune disease...etc....
At least the doctor would be able to treat them and relieve one of suffering.
One thing that works well for regular canker sores (the white thingies on one's tongue from maybe high acid, spicey foods, stress) is orajel for mouth sores. It contains zinc...and heals them up quickly.
I had one coldsore in 1976 and the next one I ever got was in 1999 when I had the flu. threw me for a total loop. My husband gets them...and in 1999 we would have been married 20 years.
Probiotic...did you do a check on the internet for pics of apthous ulcers in the mouth or canker sores? Do you match them?
*Heather* Status: mild flare enemas tapered to every 3rd night

My doc's logic.. "TREAT (FROM)BOTH ENDS" worth it !!!
