Hello,
My son is 4 and has just been diagnosed with benign congenital myopathy. He has no symptoms other than low muscle tone in his arms, shoulders and hip. He reached all the milestones early (walking, talking, etc), and is in general good health. He runs around with other kids and doesn't get tired, fall or gets short of breath--the only difference is that he won't attempt climbing, and is generally cautious.
This is my question. His pediatrician and his neurologist are telling us very different things. While his pediatrician says that he'll always be kind of clumsy or physically cautious, but otherwise, fine, his neurologist says that he'll likely develop heart problems in his 40's or 50's. We are doing as much online research as we can, but his diagnosis (benign congenital myopathy) seems to be almost meaningless, since it could have a variety of origins and thus, prognoses, and the doctors don't know exactly where his condition come from.
Armed with the little knowledge we have, what should we believe? Does he have a normal or shortened life expectancy? Will exercise alleviate/reverse this condition? What are the practical steps we should take? Where are some good resources to get more information on specifically this condition?
Finally, when he was 2 he suffered an episode of asthma and 1 year later, the same thing, but nothing in between, and nothing since. Is it related?
Thank you very much.
