First of all, I am so sorry you’re suffering for so long. I am going on 3 years in December with Long Covid, (no taste/smell, lightheaded and feel like I’m on a boat, tremors in my body if I overextend myself). I had more of the light headedness early on, now it is less often as I believe the water in my head is dissipating. I’ve had 2 brain MRI’s and it showed left sided swelling on my brain. The Chief Neurologist at Northwestern Chicago told me that this was something he thinks happened during childbirth. How he knows that, I don’t know! I believe it’s from long covid! I wish I had a magic wand to help you, but unfortunately, I don’t. He also told me that after 1 year of no taste/smell I probably won’t be getting those senses back. I pretty much walked out of there with no hope! I am a strong willed woman and am refusing to loose hope! Keep looking for web sites that are positive and keep hope alive for us living with Long Covid.
