Some injuries are already mentioned in "Disease" thread - let's invent them separately.
How is the trauma / disorder called?
What does it do?
How to gain it?
How to heal it?
Thanks a lot!
To give a few:
Already mentioned - balloonitus. For example a girl was wearing a poorly made "defence" costume for a month distorting her inflation - until a medic told her to take it off. For the first several inflations her inflated shape will be still distorted, reducing her effective volume.
* b-word is a trauma, of sorts. KABOOOOOM! No patient - nothing to heal.
* Critical ATB syndrome.
Patient feels a weak blunt pain from even slightest movement. Constantly self-inflates, so needs to be plugged into a machine constantly deflating her. Without a machine she can't stop and can't clench, billowing up to huge sizes (up to twice normal max) before popping into nothingness (without scraps left).
Cause? Having ATB syndrome and playing hero - overfilling for example.
Healing? After a week or two on deflation machine Critical ATB syndrome is reduced to regular ATB syndrome.
* ATB syndrome. Patient experiences constant weak blunt pain deep inside, and walks very carefully because of it (ATB walk), no jumps - painful. When inflated she billows too fast, and while the size is the same she reaches it with much less pumping. When overfilling, clench is painful - so it's dangerous to get full. Ability to deflate is also reduced. Sometimes spontaneous inflations happen - for no reason.
How to gain such a goodie? Almost pop yourself, or stay inflated for hours without a proper training.
How to get rid of it? First week in bed, a month of therapy (up to 3 times longer without a doctor)
* Deflatophobia. Inability to deflate.
Ouch! Once inflated, a patient stays inflated, after some weeks gains ATB syndrome from being constantly full, after some more weeks goes critical and pops.
How to gain? Stay inflated for a month straight.
How to heal? That's complicated, in XIX century they couldn't heal it. Surface cells forget how to restore information from gas. So medics use biotechnology to again teach cells how to rebuild.
How long does healing take? A few minutes, but it's filthy expensive! ^_^ Equipment is stationary, bulky and needs a genius to operate. They promise (ba)nano-robots will make healing cheaper, still promise. ^_^
Perhaps if a child witnesses someone dear to them pop (or perhaps anyone, really), they might develop Post-Explosion Stress and Trauma (or PEST). Whoever has developed it is nervous at the sight of any type of inflation, fearing that the subject may go kablooey at any second. A deep-running psychological problem, whoever happens to develop it often suffers from nightmares in which they inflate to their maximum capacity and pop. A few sessions in therapy should provide some type of aid, perhaps conquering the fear firsthand could be a possible cure...?
