About 3 months ago, after leaning over the tub to rinse my hair, I smelled a burned hair smell that lasted for several hours. I do not use hair dryers or other heat appliances on my hair and did not use any chemicals on my hair, just shampoo and conditioner. I thought it was the shampoo and decided to never use it again. About two weeks ago I began to experience that same smell again and alternatively a worse rotting odor in my nose. I can smell it most any time that I lean my head forward and down. I have also been able to smell it if I take a strong sniff . I have some nasal congestion and have post-nasal drip when I sleep. I have been using Flonase and Azelastine twice a day for the past two years as prescribed by my allergist. I discontinued both a week ago but the bad smells did not subside. I occassionally use Afrin to relieve nasal congestion. I wonder if i may have a sinus infection. I have worked at a hospital for the past 34 years and I know that an ENT will want to get a sinus CT which I want to avoid if possible due to cost as well as a preference to limit radiation exposure as much as I can. I plan to try a Neti-pot beginning this evening. Does this sound like I need to get medical attention asap or try handling it myself first?
