Interesting that they classify loss of smell as a neurological symptom. I had Covid last January and my sense of smell has never been the same. I used to be able to walk into a room, flair my nostrils, and pick up everything from the couch, carpet, and curtains… to the subtle cool drafts from the windows and fireplace. Now everything has completely dulled out, and I only occasionally pick up those old scents in passing - functioning as a cruel reminder of what I lost.
