I am so sorry to hear about your canker sores because I know how painful they are. I get them as well and also have the swollen glands and general feeling of just not feeling well. I have read that these are related to an overgrowth of yeast in the body that is caused by taking antibiotics or eating sugar. Go to the library and check out "Yeast and the Woman"...it really helped me to understand why I suffer.
