(Concern) Loss of smell after recovering from the flu

My concern is...

There is a continuous fiber smell in the air.

I thought I became more sensitive to smells after suffering from the flu severely, but even now, five years later, I can still smell a fiber-like odor from my nose.

When I smell this scent, my expression hardens..

My head is pounding like crazy..

I usually have migraines, so I am sensitive.

I can't describe what kind of scent it is, and at first I thought it only came from my house. But now, whether I'm outside, on the street, at the supermarket, or anywhere in daily life, I keep smelling a fabric-like smell, and it's bothering me because I am the only one who notices it. No matter how I talk about it, I don't think the doctors can find the cause.

Are there others who experience symptoms like mine, such as heightened sense of smell, after having the flu? 😢

No one else smells anything, but I can really only smell it myself, so it's so frustrating. I even thought about going to a psychiatrist.
