I had flu like sx about 4 weeks ago for a few days, of which a cough, post nasal drip and congestion continued. Approx a week ago I noticed I have absolutely no sense of smell or taste, it came on suddenly. I am unable to even strong smells like vinegar, pine sol, coffee, pickles., and have absolutely no taste. My nasal passages have seemed to clear the last two days yet I still have no sense of smell or taste (at all). This is not a dimished taste or smell this is absolutely nothing. I have a call into my PCP hoping they return call tomorrow, yet I am so concerned this can be permanent. I am on no medication that should cause this (Losartan only).
