I haven't been able to smell or taste for 2 weeks. i thought it was a cold but usually i only lose my sense of smell/taste for a few days. why?

Acute neuropathy: I have seen this before. In the absence of head injury, it is somewhat of a mystery. I had one patient lose her smell and taste after a flu vaccine. I think it is due to a neuropathy or acute nerve disease of the olfactory nerve, the nerve that delivers smell, which would also affect taste. I always give a trial of steroids.
