The nasal spray you are using sounds like an OTC decongestant spray (Iliaden, Otrivine or Sudafed). These are problematic as they can cause rebound blockage of the nose and worsening symptoms if used for a long time. The condition is called Rhinitis Medicamentosa. You need to use a low dose steroid nasal spray such as Beclate to weans yourself off the decongestant.
