Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you have a
sinus infection leading to symptoms of congestion leading to loss of taste and smell as both these senses are inter-related..
You will have to make a doctor's visit as it is necessary for you to get evaluated..
So in my advise you should consult an Otolaryngologist and get evaluated and he can also advise you PNS view x Ray of the sinuses to look for the problem associated with the symptoms..
He can advise you a course of antibiotics like
Azithromycin, anti inflammatory painkiller like Ibuprofen, decongestant like
Phenylephrine, Steroid nasal spray, decongestant nasal spray like
Xylometazoline, steam inhalation and saline
nasal irrigation..
Avoid chilled and spicy food and do warm compresses around nose and forehead..
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora.
