Hmmm, I never thought about it. I believe i know the reasons for my Bronchiectasis and MAC, which are largely environmental and hereditary. I don't know if the cause of fibro is yet known or understood, so I have no way to guess if there is a relationship. But it is not uncommon to find people here on Connect that share up to several conditions in common. Maybe it goes with the territory of being more "body aware" when dealing with several conditions?
