Hi..
Thanks for the query..
Well, it looks like you are suffering from inflammation of tongue and the condition is known as
GLOSSITIS.
It can be due to a number of causes like
nutritional deficiency of iron,
vitamin B12 and
folic acid, stress, allergy to certain medications,dry mouth, oral infections, Irritants such as tobacco, alcohol, hot foods, spices, or other irritants, physical trauma caused by some sharp edge of the tooth etc..
Nothing to worry, consult an oral physician and get evaluated and treatment can be planned according to the cause.
As of now you should take Vitamin B complex and lysine supplements..
You can do cold water rinses to reduce inflammation and pain.
Gargle with 1:1 solution of benadryl and
milk of magnesia..
Sucking ice pops can relieve..
Avoid hot and spicy food..
If there is some sharp tooth get it smoothed..
Hope this helps..
Regards..
