I had a L5-S1 Diskectomy partial romoval of disk and also had some knee damage and stuff and the VA awarded me 30% with out representation and I recieved the confirmation 2 weeks after discharge mainly due to the intense documentation in my records. I would say get out and take the tax free money now and if you get 20% or more then get on Chap 31 Voc Rehab and they will send you to college for 4 years and pay all of your books, supplies, tuition, fees, tutors, glasses, computer if needed, and so on you will have zero cost for 4 years of school and they also give you an allowance check depending on your dependants, i get almost $800 for that and then my $450 or so for regular dis check. It is the best program yet I have seen for vets by far! And by the way when they award your disability they only award in 10% amounts 0, 10, 20, 30.... and so on.
