Allergies or infection can do this, can't speak to the deviated septum issue (I thought once it was surgically corrected, it stayed in place unless there has been an injury to your nose that could have pushed it out of place again...). Have you tried any allergy meds (claritin, zyrtec, benadryl, etc.)?
Might be worth a call to your ENT or Allergist...
