There is a lot of mis-information in this thread. I can't correct it all. As long as your condition doesn't require medication that's not approved, or it's related to PTSD then go for it.
I'm 100% from day one...
I sent the FAA my VA rating package...
They sent back a nice letter saying two common sense things, and asking me to have my blood pressure checked and a written statement about a very miniscule issue every 6 months.
Big deal....it's well worth the $$$$$$$. You earned it...collect it.
If anyone, and I mean ANYONE is hesitant about VA disability, don't be..you are leaving money on the table. I get close to $4000 a month, don't pay a dime in property taxes, and my kids go to college for free....also get free registration on my vehicle and a hunting license.
