I am suffering from hyposmia.Am I losing the sense of smell permanently?

Hello doctor,

• I am 56 years old and I am suffering from hyposmia since a month, which appeared after a cold with fever and inflammation. 

• I have been prescribed Flixonase nasal 400 microgram/unit dose nasal drops.

• I used Flixonase twice daily for about 10 days.

• At this point I am not sick and inflammation has gone. I do not take any medication and I am healthy.

• The opthalmologist did a visual check and told me that I he could not see any sign of swelling, it was a very superficial check, just look up with the light.

I will describe how I feel my hyposmia:

• I do not have a total loss of smell.

• I can smell some things slightly, other things very slightly, and other things I cannot smell at all. 

• I have noticed that sometimes, more or less one time at every two days, I can recover a lot of my smell sense for a short time, sometimes 30 minutes to an hour followed with worsening of my smell sense. As for example, yesterday I could smell and taste my lunch and I could smell many others things like the rain outside the house.

• Sometimes I have worsening of my hyposmia and when it occurs I cannot smell many things. After a while I recover some of my smell sense more or less to the level before (not the normal level).

• Last night, my smell sense got worse but stabilized overnight. This morning it again got worse.

• The same is happening with the intensity of odors, it improves and worsens along the day. It just happens.

• Do you have any idea of what is going on?

• Are those signs of recovery or indications that I am losing the sense of smell?
