With the above clinical history,I can only suggest a symptomatic relief. Please use Mucopain gel or Dologel CT to reduce the pain while having food and speaking. Cause of mouth ulcers can be anything from nutritional deficiencies, autoimmune reasons, infections and it can be multifactorial. Treating the root cause will help you prevent such episodes in future.
Next Steps
Please consult an oral medicine or oral pathologist specialist to arrive at a proper diagnosis and management.
Health Tips
Please use the gel mentioned above about 5-10 minutes before food, so that the ulcer area is anesthetized and you can have your food properly.
