Two treatments I’ve heard of through unverified interwebs:
Ivermectin (yeah I follow that guy’s YouTube, there’s lots of study about it but afaik the usefulness for smell loss in particular is anecdotal). The mechanism would likely be that it clears out residual viral particles/pieces of cellular garbage that are causing damage.
LSD (apparently a small dose helped a guy? I think this story is on Zvi’s latest covidpost.) Obviously a lot more risk with this one and I would guess it could only work by increasing sensory output because psychedelics. (This kinda tracks with the essential oils suggestion? Sniffing stuff a lot could rewire some neurons I guess.)
Good luck!
The medical examiner thing seems totally fine—in this county they only see bodies that are sent for autopsies; i.e. something is fishy about their death. If you die in an ICU because of low oxygenation you don’t get sent to the medical examiner. If you die from a knife to the back and your family wants to argue that you died from COVID-19 then it makes sense for the medical examiner to want them to pay for it.
