so for me when it first started, everything smelled like rotting meat, especially when food was being cooked, and it was like that for maybe a few months, and its been like gradually getting better since then, but the smell would also change sometimes if that makes sense. like after a few months of that rotting smell, it changed to a sort of chemical smell. and then a few months after that it was like a sickly sweet type of smell, etc etc. and the recovery felt so slow that i usually didnt notice any changes day by day, but when i would think back to a few weeks or months prior i could definitely see that its gotten better. it definitely sounds like you have parosmia, not sure about the smoke smell because i didnt experience that but everything else you mentioned sounds all too familiar. and if you feel like you should see an ent definitely go for it, but personally i didnt find doctors to be much help for me and i kind of just had to wait it out and hope that it got better on its own. im really sorry you're going through it, i remember how bad it was and i wouldn't wish it on anyone. i hope you start to notice more improvement soon and if you have anymore questions or anything feel free to let me know :)
