Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain hurting of throat can be due to infection in throat caused by either bacteria or virus and it can lead to
sore throat..
A split over the tongue can be either due to physical injury caused by biting or can be due to injury with some hard and sharp food..
It can also be due to inflammation caused due to
throat infection or can also be due to
nutritional deficiency of iron and Vitamin B12..
I would suggest you to consult an Oral Physician and get evaluated and he can do a thorough clinical evaluation and treat you accordingly..
As of now you can do warm saline gargles, gargle with a numbing mouthwash containing Lignocaine, take
multivitamin supplements and avoid hot, spicy and hard foods..
Drink plenty of water and maintain a good
oral hygiene.
Hope this information helps..
Thanks and regards.
