I hope I can help someone!
I am 100% service connected for a condition that was exacerbated by service. It took me 19 years to get a full rating. What I most want to say, is that if you are refused benefits for a pre-existing condition, don't give up! My last job was as an Assistant Department Service Officer for the American Legion. If anyone has questions about the claims process, I can try to help. Best of luck, and I thank all for their service!
