Hi.
Can understand your concern..
As per your complain burning sensation of tongue without any visible problem with the tongue can be due to a condition known as "BURNING MOUTH SYNDROME".
It can be without any known cause and in that case it is known as Primary BMS.
It can also occur due to certain other reasons also known as Secondary BMS like
Dry mouth, effect of some medicines like blood pressure medicines,
fungal infection,
nerve damage,
salivary gland dYsfunction, Sjogrens syndrome,
vitamin deficiency, diabetes, dentures etc.
You can very much relate if anything I described is causing you the burning of tongue..
I would suggest you to consult an oral pathologist who can take a detailed medical history and clinical examination and pathological investigations can help in finding a correct diagnosis.
A correct diagnosis can help in planning a proper treatment.
A few things which you can do at home is to sip on more of cool liquids.
Avoid taking hot and spicy foods.
You can apply numbing gels on tongue in case of severe burning.
Hope your query is solved..
