Everyone in my family (5 people) developed primary symptoms but me (33 years old). I had a very strange course of leg/muscle pain, scratchy throat the first month then chest/arm pain for another month with GI issues the next. My 3 year old niece who had beaten the primary symptoms relapsed with a fever end of September and right around that time I started getting neurological issues where I was dizzy and had a burning cheek and buzzing/tingling fingers/toes with mild muscle twitching in my face.
6 months later I’m much better but still grappling with dizzyness and nerve pain in my cheek which sounds similar to you.
I’m convinced my immune system is going nuts from exposure to Covid and I fear I may have developed a more long term auto immune issue.
Probably time I take these symptoms to a neurologist.
Did the Dr prescribe you anything for your myelin damage?
