Blocked Nose, Itchy Sensation and sneeze

Dr. Jagdish Chaturvedi I have been suffering from sneezing, blocked nose from last 45 days or more. Consulted with two doctors . They somewhat gave me similar medicines and till date things have not improved much. I was told to avoid AC , but my work does not allow me to avoid it. I kind of spend almost 5-6 hours under AC. I have taken following medicines till date : Droxyl 500 - 1strip Sinarest tab - 1 strip Montair Fx- 2strips Otrivin nasal spray Sinarest nasal spray Steam inhalation once a day These days, my nose and sometimes face, neck fells itchy before I sneeze and in morning just after I wake up, I have a blocked nose. I am tired of the cold, blocked nose and sneeze from last one and half month. Please help.
