I think it is like some other neurological conditions. You have a genetic predisposition, a prolonged period of being in 'fight or flight mode' (whether it is abuse, caring for sick family, stressful job....) and then a triggering event (illness, accident, injury...) creating the perfect storm. But then we must remember that it sure seems that type A personalities are more prone to. So, it's nature vs. nurture again...There's a clear answer :)

No it is not i was told by doctors.

Yes it is hereditary. My paternal grandfather had it, his daughter and son (my dad) have it. One of my aunts daughters have it (2 daughters do not have it). Both my brother and I had it and my son has it. None of us had a bad life or anything unusual, just fibro.

My mom had it but hers didnt

My husband has it as do all 6 of his sisters and of his neices n nephews 12 nicest have it n 2 nephews yet his mom doesnt have it but it is suspected his dad had it (his dad died of cancer a year after his birth) but never got a disnois as he died before he was 35.

And my paternal grandfather had it, they just didnt know what it was at the time
