Welcome to HCM.
Understanding your concern.
Thanks for your concern . The symptoms you mention in query are clearly pointing towards a condition known as cancer sore . These occur due to various factors like hot and acidic food , any injury to mucosa , stress , hormonal
changes or some medicines. As you have previous history of Stevens Jones Syndrome, your immunity of oral cavity is low and mucosa is highly susceptible for sores.
They usually go away within few days by their own.
I would suggest you to :-
- Start doing warm saline and baking soda rinses .
- Apply orabase gel before having meal to reduce burning sensation.
- Do betadine
rinses also for twice a day .
If condition doesn't subside in a weak then consult oral pathologist for proper diagnosis and then go for biopsy by taking sample from oral mucosa
Doctor may prescribe steroid
ointment or drug like sucralfate
Also start taking Vitamin B complex supplement. Avoid drinking and smoking.
Hope your concern has been resolved.
