question: For the past couple of weeks I ve been smelling a very bad smell that no one else says they smell. I ve also had a very bad taste in the back of my throat. I ve experienced a couple of episodes where I ve been very dizzy, during one episode I felt as if I was going to pass out. I don t have a cough, sore throat, or nasal discharge. I have traveled frequently by airplane over the past 2 months. Any thoughts as to why I m might be experiencing the smell?
