Finding a functional medicine doctor can be really helpful someone who is highly educated at looking outside the box and treating alternatively. After 8 months post vaccine injury and many of the same long Covid haul symptoms including the vibrations and twitching , and having every test under the sun, my diagnosis was that dormant viruses have been activated in my body - viruses we don’t even know we are carrying. And that is why we have a host of symptoms that don’t always make sense under one condition. Being treated with natural remedies as I was also diagnosed with hypersensitivity disorder through this process by an immunologist. Finally feeling like things are moving in the right direction. Good luck - this is a long journey.
