Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain all the symptoms are pointing towards
sinus infection or sinusitis and ear congestion seems to be secondary to sinus infection leading to
post nasal drip that is causing fluid accumulation behind the eardrum..
I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and 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 being in airconditioned atmosphere
Do warm compresses around nostrils and also you can be advised antibiotic and analgesic ear drops..
Hope this information helps..
Thanks and regards.
