Thanks for writing to H.C.M.
I have concluded yur complaints regarding sore throat
and blckade in right ear. As you said this is for last 10 days swelling at the root of your mouth and back of throat on right side.
You are suffering from acute pharyngitis
with eustachian catarrah. This actually happens because throat infection
has reached to involve eustachian tube at pharyngeal end and ultimately due to infective oedema this tube had been blocked thus you are feeling blockade of ear.
You have asked weather it s bacterial or viral this can be decided only by Culture and sensitivity of throat swab.
Since you are not having any nasal symptoms so sinusitis
is unlikely in your case.
You may take -
(a) Antibiotic- preferably broadspectrum.
(b) Anti inflammatory & Analgesic
(c) Decongestant & steam inhalation.
I hope this will help you.
