Hi,
You should consult an ENT specailist or allergy specialist for your symptoms. It would require a proper clinical examination and evaluation to come to a confirmed diagnosis.
Till you get an appointment you could take OTC antihistamine medications, saline nasla drops and steam inhalation. This should help with your symptoms. When the pain is severe, take some OTC pain relief medications.
Your doctor would prescribe a course of antibiotics and some steroid nasal sprays.
Do let us know if you have any doubts.
Hope this helps.
Good luck.
