First of all, I’m so very sorry you’re suffering so much. It’s awful not to get answers, I know about this as well. I’ve suffered with no taste or smell for going on 2 years in December. I’ve had treatments of Stellate Ganglion Block Injections and they bring slight help, but nothing lasting. I try to keep busy and I have to say I don’t make plans with friends, because it’s usually dinner or lunch and not having any taste or smell along with several food sensitivities makes it difficult. I wish you good luck on your health journey.
