HI
You are welcome in HCM.
I have gone through your query regarding your recurrent sore throat and swelling of tongue.You have told that you are a patient of sinusitis and there is continuous flow of fluid in your throat.
Considering your symptoms I would like to tell you your root cause of illness is your sinusitis which time to time puts out infected discharge in your throat and give rise to soreness. This sometimes when appears in severe form give rise to infection in nearby structures like base of tongue and uvula and palate etc
You are now advice fr following basic investigations-
(1) C.T.scan of paranasal sinuses.
(2) culture and sensitivity of throat swab.
(3) Blood- C.B.C., E.S.R., blood sugar (fasting & pp )
After this you should contact an E.N.T. specialist for thorough clinical examination and clinical co-relation of inferences of investigations to make final and complete diagnosis and pan for treatment.
Hope your query is now clear but still if you have any doubt your re consultation will be welcome.


Regards with thanks.
