I have been having blocked/ running nose and cold from mid of January. Starting I had itching in my throat throat pain and dusty feeling with cold . But now presently I have running nose all the time when I get up in the morning and throat doesn't feel right as if there is dry phelgm and I have recently become very sensitive to dust or dusty feeling and I get running nose or sneeze. I'll tell further about the instances how it occured once I get in touch with you.
