well people with hypermobility (not just a ltitle but A LOT , like eds http://fmshmscfs.bravehost.com/myPictures/phpX686v5.gif)
nothing is stable. cutting out a rib would help someone with an extra rib definitely but if a rib is just hiked up because of the scalenes which are turned on bc the neck isnt stable from fhp. hypermobile people need stability. for example, i used to think there was something wrong with my pec muscles until i saw my back

not only that but surgery=scar tissue. our tissues are really sensitive.

this is all just my opinion anyways
