I know all about how hard this one is Puc. I've had it a few times myself last one being with the "Flail Chest" thing but that one came back pretty easy with the damage I had. Had one in 76 that didn't want to reinflate. They had to put tube in my chest which is NO FUN!! He has the tube now Again!! Yeah I think it plain crazy that they say it just happens. Can't accept that. This young man is very active. He is a Woods. His mom is very anti motorcycle so he don't have that one but does the bikes, skateboards. trees, boxing and all that stuff. It doesn't just happen but I never had restrictions after it healed when I had one and his is just colasping again without a reason. I know I'm going in circles here but this thing just don't make sense. Beginning to scare the boy I think along with a few others. I'll keep ya posted on what is happening just not much news from the Idiots (docs). Not understanding that either. Thanks for Prayers!!! "The Man" can take care of him.
