Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain Muffled hearing can be caused due to causes like
Eustachian tube dysfunction due to clogged Eustachian tubes, fluid behind the eardrums,
inner ear problems etc..
I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like
x ray, MRI Scan etc can help in diagnosis and treatment can be done accordingly.
If there is fluid accumulation behind the eardrum and the decongestants and other
sinus medications are not working then you can be advised to get surgical
drainage of the ears done to relieve the blockage..
As of now you can chew sugarfree chewing gums as at times it helps in relieving clogging..
Taking steam inhalation can also help..
Hope this information helps..
Thanks and regards.
