Hello and welcome to HCM
You have not mentioned which of your glands are swollen.
You need to take saline gargles and pain killers for sore throat
If the throat is aching you need to consult your doctor for prescription of antibiotics.
Muffling sound in the ear can be due to blockage of eustachian tube.
Eustachian tube is a tube which connects the middle ear with throat.
the end of the tube which opens into the throat can be inflammed due to throat infection
Consult an ENT specialist
for both the problems.
Thanks and take care
