Hi,
Since when have you been having these symptoms?
Do you have associated symptoms of fever, sinusitis or rhinitis? Is there any past or family history of allergic reactions?
Have you tried any medications for your symptoms as yet? Have any investigations been done? It would be advisable to get a chest xray, and CT scan of your sinuses done.
You need to consult your doctor for a proper clinical evaluation and to rule out sinusitis, rhinitis, pharyngitis, asthma and any allergies as the cause of your symptoms.
Till then you could try warm saline gargles, steam inhalation, oral antihistamine medications and see if it helps with your symptoms.
Let us know if you have any other doubts and post us about how you are doing.
Regards.
sounds like you're allergic to something. allergies can come on at any time, at any age. even if you have never experienced them in your lifetime, they can start at any given time. check with an allergist or maybe even an ENT (ears, nose, throat specialist). good luck!
