I am 34 years old. I have one small mouth ulcer on left side of uvalla means on soft palate. It's as it is since 6 months and some spot type appears but no pain etc. No problem in eating etc. I am simple pure vegetarian person and having simple lifestyle. Never drink smoke etc. Yes I am using homeopathic medicine for sinus nose blockage problem since 1 years but now relief in sinus. Kali bichromicum is prescribed by doctor to heal that mouth ulcer but no improvement. Pls suggest any suitable medicine so that that mouth sore/ulcer may be treated permanently.
