Thanks for asking the query,
After reading your symptoms i think you have developed a condition known as Burning mouth syndrome
The symptoms include burning sensation of tongue, lip and palate as well.
It occurs due to nutritional deficiencies, allergies, and trigerred by stress, anxiety and depression
I would suggest you to;
- drink water frequently.
-Avoid spicy food.
-Avoid alcohol or tobacco products.
-Maintain a good oral hygiene
Hope this helps out.
