My nose has has been blocked for almost 3 months now. i have been using illiadin daily to open my blocked nose but it only opens it for a few hours.

Common disorder: The stuff you squirt up your nose works by constricting capillaries that produce the fluid within the nasal tissue. If used for a day or two it works well. Once you use it every day you cause a chemical burn in your nose that hurts the capillaries, makes them leak so the tissue swells. Quit for a few weeks. If a nasal steroid like rhinocort is available it may speed recovery used 1-2X/d.
