Yes, I have had 3 so far and will be going for a 4th in a few weeks. I lost my taste and smell in December of 2022, due to Covid. Here it is April 2024 and only a slight improvement with the injections. They are used, in my case to increase taste and smell. It has only helped minimally, where I get a stronger salty, sweet or sour/bitter taste in my mouth, no flavors however. I can smell ground coffee almost every morning, but the scents are fleeting. I live in the Chicago suburbs and have these injections done at our Northwestern Hospital in the city of Chicago’s Pain Management Clinic. They use an ultra sound to guide them where the injection needs to go into your neck and inject you with Lidocane. It isn’t painful, but the side they inject you on, your eyelid will droop for a while and your sinuses on that side will be stuffed up for about 2 hours. Other than that, it’s quite painless. If you’re considering doing this, be sure you’re going to a reputable hospital that knows what they’re doing. I’ve been told Cleveland Hospital is doing it as well. I wish you all the best!
