I caught Covid in November of last year and my sense of smell and taste were definitely dulled for a few months. Lately both seem to have recovered, but I'm now constantly smelling woodsmoke whenever I go.
We do have a pellet boiler in our house, but I've never smelled it before (it's well sealed) and I'm still smelling it in the car, at work and when I'm outside so I'm sure it's not a smell lingering on my clothes or hair.
It's very weird and I'm wondering if anyone else has experienced this - I think phantom smells can be a sign of something neurological so I probably need to mention to the GP - not sure how worried I need to be.
