Thanks for your tip/reply. My sense of taste/smell is much better now and seems to be on a good trajectory as well, I won't seek more treatment at the moment. What you describe kind of sounds related to a stellate ganglion block[0] which can have these instant (and for some permanent) effects on covid-induced anosmia.
I was referring to scalp acupuncture as a maybe-potential-who-knows remedy to the Aphantasia, but it's a projection of it curing my smell/taste in minutes, not a "scientific assertion".
It's not the same as described in the link. I'm referring to acu needles at the top of the scalp in specific locations, triggering whatever nerves are there.
Covid was/is a weird one. Hope you get your visuals back. I've never had them but if I did I wouldn't want to miss them.
