Just a quick word of advice. If you sustain an injury while on active duty, don't wait until you are out of the service to file a claim with the VA. Do it while you are still active! You can do a "quick start" claim if you have only 60 days of active duty remaining, or you can be super proactive and file when you have more than 60 and less than 120 days remaining; with that option, your benefits will start at discharge. It's called the "Benefit Delivery at Discharge" or BDD program.

I am working with my local Veterans Service Office (VSO) to file my claim. We'll see how it goes! I put it off because like many people, I felt like "I'm fine, I don't need to do this." But with injuries like mine, it's not about how I feel now, but how I feel later when I need a hip replacement or some of my other service-related ailments get out of control. Haha.
