hello and welcome to HCM,
Since you have allergies, do you constantly rub your nose when you sneeze or when there is nose discharge? If yes then avoid rubbing or meddling with your nose and always use a clean cloth to wipe the nose.
Furthermore have you undergone a complete physical with blood testing with special emphasis to sugar levels? If not then it is advisable to do so.
After the above two I would suggest you to see your ENT who would like to take a CT of the sinuses
and nose to better understand your problem and offer you a permanent solution
