Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain burning sensation in mouth with red tip of tongue can be due to Apthous
Stomatitis leading to inflammation inside mouth..
It can occur due to side effects of medication if he takes any, deficiency of iron and
vitamin B12, stress, physical trauma to the tongue, allergies,
acid reflux etc..
I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigations like blood tests can help in diagnosis..
Treatment of underlying cause will relieve the symptoms..
As of now you can start gargling with a numbing mouthwash containing Lignocaine to relieve the symptoms.
You can also take a
multivitamin tablet daily..
You can take anti inflammatory painkiller like
Ibuprofen..
Suck ice and do cool water rinses..
Avoid spicy food..
In case of no improvement consult an Oral Physician and get evaluated..
Hope this information helps..
Thanks and regards.
