I am a retired Radiation Therapist. 2 years ago I had pneumonia twice about 6 months apart. I was on antibiotics for almost 6 weeks injections and orally. I noticed that I lost my sense of smell and to this date have not regained. It drives me nuts! I use to love to be able to smell soap , the ocean, fresh mowed lawn, food cooking etc. I went to an ENT and he could not find anything wrong and even did an MRI and nothing showed up. He told me I would probably never regain my smell. I can live with it , but you do not realize until it's gone how much you depend on your nose. The other day I had a fire in my oven and could not smell the smoke , just got lucky that I was in kitchen and saw it. I have allergies and have not been to an allergist because other than itching and swollen eyelids the bottom not the top ,that is all the symptoms I have. I have no mucous or green drainage. Can anyone suggest something? Once in a while I can get a small scent of lemon if I am cutting a lemon. Sometimes I get a metallic smell and it will last a couple of days. I am at wits end.
