question: Hello doctor,I have been dealing with a sinus odor problem for years. I am a fair online researcher and I have been shocked by how unique my problem seems to be. The odor varies in strength and seems to disappear and return over time. I have seen numerous ENT specialists over the years and with the exception of one, they seem to be totally baffled by what is going on. This is an odor that at times, it can be so strong that people can detect it when I walk into a room. Using Mupirocin in my nostrils and I am also doing the upside down nasal rinse with saline solution and peroxide. I thought they were helping but I am starting to have my doubts. I was addicted to nasal spray for many years and I am worried that I did some damage to my sinus cavity. Please advise.
