Hi XXXXXXX thank you for posting your query on health care magic.

Looking at your symptoms, you might be suffering from Sinusitis.The cause might be allergy or blockage of sinus opening due to mucus.

You may find relief by taking the following:
1.)Oral Decongestant (like containing Phenylephrine) if you are not suffering from Hypertension and Nasal Decongestant drops (like containing Oxymetazoline)-the Decongestants help in decongestion of nose and sinuses
2.)Mucolytic (like containing Ambroxol)-it helps in breaking of mucus secretions collected in the nose and sinuses
3.) Analgesic (like containing Ibuprofen)-it will help in reducing the headache,pain and reduce the Inflammation in nose and sinuses
4.)Antacid( like containing Rantac)-it helps against the increased acid formation due to Analgesic and also in few cases,the cause of long term sinusitis is Acidity and acid reflux.
5.) Antihistaminic (like containing Cetrizine)-it helps in allergic symptoms like watering from nose, itching, sneezing, watering from eyes
6.)Steroid Nasal spray (like containing Mometasone)-it helps against the nasal allergy and reduces the Inflammation in the nose and sinuses.
7.)Saline nasal spray-it helps in maintaining moisture in nose,to remove any irritating particles from your nose and is also a mild Decongestant.

You should take following home measures:
1.)Steam inhalation-it will help in breaking of secretions.
2.)Drinking lots of fluids (warm)-it will also help in breaking of collected secretions.
3.)Avoidance of things that make your symptoms worse(like certain foods,Dust,etc)
4.) Avoidance of cold and very sweet food as they increase the mucus secretions.

If you are suffering from severe headache,pus discharge from nose,fever,etc which suggests bacterial infection,then you might need to start Antibiotics after consulting an Otolaryngologist Doctor.

If after following the above measures,if your symptoms are not improving, then it would be advisable to consult an Otolaryngologist Doctor.He/She might do nasal endoscopy and CT scan of paranasal sinus if required and treat accordingly.

Hope this answers your question.I would be happy to answer if you have any follow up questions.Get well soon.
