i couldnt find the actual link that i was looking for, but i came up with this. i remember when i DID find the website talking about somethng that sounded similar to what your brother has i was looking up ways to reverse atrophy.
What is Spinal Muscular Atrophy?
here's the link. it's mostly about sma, which is similar to what were going througha nd possibly your brother. i will continue to try to find the link to the site i originally thought sounded a lot like your brother, however the more i thought about it i really hope the site i meant to post is not what your brother has. in it, it talked about how the lower and upper extremities atrophied and after a while it progressed to more vital muscles like the lung and heart. it was quite scary to read about because after i read it i started looking for more signs of wasting on my own body.
i am going to get a flight physical soon to see if i will be able to fly afterall. the more the atrophy progesses the more worried i get that i am going to college for nothing. i keep trying to do stuff to build the muscle back but nothing seems to work. my body does not want to cooperate, its very frustrating. i wonder if when it stops like they say it does, or IF it ever stops, if i will then be able to rebuild the muscle. i think the worst part is juST waiting to see what will happen. i'm still trying to live life to the fullest, but whenever it hink about the future its full of questions. thats why its better to just live for NOW and think about the rest later.
