@Breezy Yes sadly most doctors haven't heard of it and if they have some don't think it's actually a thing. I'm very lucky in having my mum that also has the same condition so it's nice to know i'm not the only one going through things.
Also no one knows if it is genetic there has been very little research about it let alone in that area. Glad you came to comment hope your mother has learnt to deal with the pains, fog and tiredness.
