Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that discharge of yellow snot along with sinus pressure and ear pressure is an indication of infection in the sinuses leading to Sinusitis and pressure in ears can be due to fluid accumulation behind the eardrums and also
ear infection..
As the
post nasal drip contains infected mucous therefore it can cause infection and inflammation in throat leading to sore throat..
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 spicy and chilled foods..
Do warm compresses around nostrils..
Hope this information helps..
Thanks and regards.
