I have FSHD too, was only diagnosed 18 months ago aged 41 when getting physio after a broken collar bone. Fortunately fairly mild and doesnt restrict me that much. My dad and brother are the same.
I have 2 kids (both well before diagnosis) so didnt have to make the choice then. Would I choose differently now? – I don’t think so. It hasn’t massively affected my life, and advice is that the severity tends to be similar as its passed on so hopefully won’t affect the kids too much as it develops. They certainly have a pretty good quality of life now and hopefully always will.
Now we know about the condition, the difficult questions will come when they want to start their own families. But hopefully Tonyg and his friends in white coats will have fixed it by then 🙂
