Hello
Welcome in H.C.M.
I have gone through your query regarding your ear pain and loss of hearing for about a weeks time. you are having cold and when you clean your nose you get buzzing sound in your ears. you have already visited a doctor and as per advice you are taking antibiotic which had made you free from pain but fullness in ear is persisting.
Considering all these development I would like to tell you since this antibiotic had help in pain so no need to change it but you should add anti inflammatory , anti histaminic and decongestant like steam inhalation etc in your treatment. In this way you will get the response.
Hope your query is explained.

With Regards.

Hello Katherine..
The symptoms as mentioned in your post suggest that you might be having Serous Otitis media (Otitis media with Effusion/Glue ear)
In this condition...the middle ear cavity gets filled with serous fluid, resulting in congestion and bulging of eardrum, sensation of pressure in ears & interference with transmission of sound (conductive hearing loss).
Management is based on diagnosis by physical examination & tympanometry.
So...it will be better to consult an ENT specialist & get a proper physical examination done to find out the exact cause.
So that proper management steps could be taken.
Wishing you a Good Health. Let me know if I need to clarify further.
Thanks & take care.
