Allergies: If you do not have a cold, this sounds like nasal allergies. Try taking over the counter Claritin or Allegra and see if they help and if not see your doctor.

Allergies: If this has become a chronic condition, these are often symptoms of chronic, low-grade allergies. You might experiment and take some otc zyrtec (cetirizine) for a week or two. If it helps, i suggest possible allergy testing and further evaluation and treatment with either medications or allergy shots.

Allergic rhinitis: It looks like you might have allergic rhinitis. It's a common condition but if not treated it can lead to more serious problems like chronic rhino sinusitis. You would need to see a local allergist to be evaluated.
