Even with top-notch medical care and money, it can take doctors years to figure out a diagnosis with symptoms as non-specific as what this condition causes. I saw that with a good friend's mom.
But having a diagnosis does help bring a sense of closure and stop the "am I crazy?" feedback that happens when you know something is wrong but doctors either say there isn't or they can't figure it out.
Sending prayers to the whole NRF and especially MM, Haakon and the kids.
