if i get a uncomfortable and watery nose all the time.does that mean i am allergy to dust.sometimes, my nose start to itch and i always feel like sneezing.
You may be suffering from Vasomotor or Intrinsic Rhinitis which is due to stress and not due to any allergy.
Need not be to dust only, but that is the most common one. Do get a Allergy patch test done to confirm it.
