Tell us all about your injuries/disability. I'm curious.
Eh sure, why not.
My right arm was broken backwards at the elbow during a training accident while I was prepping for Afghanistan. We were brushing up on our hand to hand combat skills and the guy threw his entire body weight on top of me. (We were both 200+ pounds.) Suffice it to say my bones shattered like sugar cane, bad enough that there was significant bone marrow edema. My ulnar collateral ligament separated from my ulna, taking a piece of bone with it. Some of my nerves were stretched so far that they were torn from the muscles in my forearm and hand. All of that could have been recovered from, but my Sgt. relocated my arm while I was passed out / halfway delusional from the pain. Not sure if it was before or after I blanked. Just heard it happened from my friends who were there. They put my arm back in assuming it wasn't broken and didn't send me for medical treatment, told me all I had was a dislocation. The next day I went to medical for some pain meds because my elbow as the size of a softball. When they did xrays, examined the arm, etc... they were horrified.
Long story short, a series of bad doctors and physicians assistants refused to give me surgery to relieve the pressure in the arm. I ended up with pretty significant nerve damage. Arm went from somewhat functional to paralyzed for quite a few months. Took over six months to be able to hold a cup again. With the years it became... reasonably functional. I have no strength in it though. I drop things all the time.
I never was given surgery to repair any of the structural damage. After being examined by the surgeons at my next station, they realized I had Ehlers Danlos Syndrome (mutated collagen.) I'm a bad candidate for repair; you could end up having to repeat the surgery five times. Also, my skin tends to rot whenever my arm is in a cast in a matter of less than two weeks. I also atrophy about 5x faster than a normal person so post surgical immobilization isn't a possibility. You could use cadaver parts in me, but eventually my body would regenerate them with my screwed up collagen again. So it's kinda pointless.
I also had a translongitudal split tear of my peroneus brevis tendon in my ankle that left me with an unusual gait and led to weakness in my right knee. Now I walk with a cane due to dislocations.
I have a torn muscle in my back that re-tears every few years now. I also have torn both of my rotator cuffs and they continue to re-injure every few months. Again, no one wants to give me repair surgery because of the EDS. I don't blame them. Now I just live a careful life.
I also had some.... well, let's just say I didn't adjust well to the loss of the use of my arm and ended up with a fair anxiety problem. While manageable, I'm far from a normal person. Touch agoraphobic, antisocial, etc...
Technically my combined disability rating is 90%, but they pay me at 100% because I can't be hired for my previous career (Correctional Officer.)
Veterans affairs uses fuzzy math to combine disabilities. If you have one rated 50% and another at 25%, you aren't 75% disabled. They take 50% and (25% of 50%,) giving you 62.5% disabled. To get to 90% I had to have injuries at 50%, 50%, 30%, 10%, and 10%. They round up from there.
Edit: forgot to mention the never ending pain in the arm. It never stops and I'm super prone to drug allergies so I avoid meds. For an amusing example I'm allergic to solumedrol.
Here's an awesome old video of how the arm was working six months after the injury.
Back in 2010
I consider myself very fortunate and would do it all again. I just wish they had retained me instead of giving me early retirement. They retain the amputees... 15 degrees more of rotation and that probably would have been me.
