Hello, my name is Dr.Dorina Gurabardhi. I understand your concern. 
The 
sinuses are hollow pockets within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen due to inflammation, it can block the sinuses and cause pain, congestion, post-nasal drip, a 
cough, and tooth or 
facial pain. 
Some advices that I can give to you for 
sinusitis are:
-Flush your nasal passages.
-Hot water vapor can help moisten the sinuses.
-Stay hydrated 
-Spicy foods such as mustard, hot peppers, curry, horseradish, and wasabi may help clear sinuses.
-Allergy-proof your home. 
-Use a humidifier. 
-Apply warm compresses.
-Don’t ask for antibiotics right away. Using antibiotics can lead to 
antibiotic resistance so try first this advices.
