No, you are not alone in this loss of taste and smell. I lost mine in December of 2022. I’ve had now 7 Stellate Ganglion Block Injections and they haven’t brought back my taste/smell, but have taken some of the jitters out of my body. I guess it’s anxiety, which I never had before Covid. The doctor I see for the injections works out of Northwestern Hospital in Chicago, Il, he doesn’t have answers either. It is frustrating…I guess all we can do is wait.
