Hi Dear Chaitali Banerjee, Welcome to HCM. Understanding your concern. As per your query you have symptoms of recurrent herpes infection which occurs due to poor immunity of body. Once herpes attacks body , it remains latent in nerve endings there and become reactivated again whenever immunity of body is low. I would suggest you to start with antiviral drugs such as acyclovir, famicyclvir. Maintain proper oral hygiene by brushing and flossing on daily basis. Rinse with antimicrobial mouth wash such as listerine. Start doing warm saline and baking soda rinses . Apply orabase gel before having meal to reduce burning sensation. Also start taking Vitamin B complex supplement as it will boost your immunity. Avoid drinking and smoking. 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. Hope your concern has been resolved. Best Wishes, Dr. Harry Maheshwari
