Hello,
If you have already taken two courses of antibiotics,you should not take any further antibiotic without proper investigations.
Consult a ENT specialist and get a
CT scan of
sinuses along with a nose swab culture.
Till you consult an ENT,do the following...
Take steam inhalation three times a day.
Take hot liquids and soups.
Avoid cold drinks and use of ice.
Take some anti inflammatory like
ibuprofen 400 mg three times a day for few days.
CT scan will tell whether any surgical intervention is required or not.
Thanks
