Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that there is fluid accumulation behind the eardrum along with clogged Eustachian tube and it is leading to muffled hearing and pressure in ears and pressure around the nose is also due to inflammation in the lining of the sinuses..
It is due to infected sinuses only..
I would suggest you to consult an Otolaryngologist and get evaluated as taking
Claritin D alone is not sufficient..
You can be advised investigations like PNS view x ray or MRI scan can help in diagnosis and treatment can be done accordingly..
You can be advised a course of antibiotics, anti-inflammatory painkiller like
Ibuprofen, decongestants like Pseudoephadrine, do saline
nasal irrigation, steam inhalation and use a humidifier in your room..
You can also be advised decongestant nasal sprays containing
Xylometazoline or
Oxymetazoline..
Avoid spicy and chilled foods..
Do warm compresses around nostrils..
Hope this information helps..
Thanks and regards..
Dr.Honey Nandwani Arora..
