I don’t have any suggestions, but I hope you’ll get some. I was diagnosed with post covid syndrome by my ENT at Duke Hospital, confirmed by Duke neurologist. My other doctors accepted it. I’m not sure how others, including my family , felt about the diagnosis mattered. Their opinions didn’t impact me. Also, since there isn’t any real treatment for LC, the diagnosis wasn’t of any real benefit to me either. For me, convincing others the reality of LC isn’t a priority.
