This is probably the most relevant forum I have found while dealing with parosmia, hyposmia, and partial ageusia. I am a 46 year old female who had COVID in April 2024 and lost all sense of taste and smell. With a combination of ENT visits, smell training, binaural beats and meditation it took a couple of months to partially regain them, but as they returned, I developed parosmia. Over the past year and eight months, I have experienced little to no progress beyond that initial recovery, with only a few odd moments of brief improvement and even one gas-leak scare that, thankfully, my daughter detected.

Yesterday, I underwent a medical procedure and was under general anesthesia for about 20–25 minutes. When I left the office, I realized there was significant improvement in both smell and taste, and I am truly hoping it lasts. I am also surprised that there are not more studies on this, aside from the stellate ganglion block research...
