Hello, how are you? I d like to ask you something, I ve had this dry cough since Thursday, I started cleaning my garage and I inhaled a lot of dust, since then I ve been having a nonproductive dry cough, I feel horrible, it is so upsetting, sometimes I think my lungs are going to come out of my chest, my head is about to explode, I have a terrible headache due to severe cough. I ve taken NyQuil, DayQuil, and Mucinex DM, nothing is helping. I don t have a fever, or sore throat, just the irritating cough, please help, thank you, Michelle
