Have you tried these? https://www.amazon.com/BarberUPP-Green-Stix-3/dp/B00QIZVTN8/ref=sr_1_2_s_it?s=hpc&ie=UTF8&qid=1498765054&sr=1-2&keywords=silver+nitrate+sticks I tried them because my ENT appointment never got made to cauterize cankers. I'm too chicken to use silver nitrate on myself but these sticks, produce pain that drops me to my knees for an hour, and then no more pain for ~12 hours with significantly faster healing time.

I just bought the Kank-A medicine on Amazon so hopefully if I use that in conjunction with those sticks, it will lessen my pain. What triggers cankers for you?
