Hi Dear,
Understanding your concern.
the symptoms you mention in query are pointing towards a condition known as
pharyngitis . Pharyngitis is inflammation of the pharynx that is the back of the throat. This can cause a
sore throat, as well as scratchiness in the throat and difficulty swallowing and that give you a discomfort at the back of the tongue .
Viruses are the most common cause of , but sometimes caused by bacterial infections.
I would suggest you to
consult ENT specialist for proper examination .
Doctor may order blood test ,
throat culture or X-ray of upper respiratory track .
Doctor may prescribe antibiotics (penicillin or
amoxicillin) along with anti inflammatory .
Till the do warm saline gargles , avoid hot and spicy food and also do betadine gargles .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
