I’m so sorry you’re suffering. I too lost my taste and smell with Covid in December of 2022. Needless to say, as you all too well understand, that it’s awful! I have had 5 Stellate Ganglion Block injections and they’ve only slightly helped, meaning that I have a stronger sense of salty, sweet and bitter sensation on my tongue, but that only seems to last for a few weeks. I have yet to taste a flavor of any kind since 2022. Were your plasma platelets injected into your neck? That is where the Ganglion Block injections are injected. I’m curious because I haven’t done that yet and may give it a go next time. I don’t do the smell training kit any longer, because it gives me a headache trying to smell something I just can’t. I’m looking forward to hearing about your plasma platelets. Thanks!
