I was chapter 61 retired 10 June 2019. I filed my VA claims after receiving my DA199 in may. The claims I filed didn't have LOD's because they weren't injurie's. In the guard they don't issue LOD's for illness's, just injuries. I filed claims for everything that was on my DA199, The VA took 4 months to decide what was on my DA199 WASN'T service connected.
You have a couple issues going on here. Anything you have an LOD on that is In the Line Of Duty (ILOD) will be considered as service connected. Everything else, as a guardsman, has to be in your medical records. If it isn't, now the onus is on you to prove that it is service connected, and best of luck with that endeavor.
The VA is a different animal as far as C&P stuff. You can say a whole bunch of stuff is service connected on the DA199 to the VA and they will look at it, but upon review of your records, if they don't see it, they will deny service connection.
If you don't already have a copy of your medical records, you need to get one. Comb through it and see what items you have in there. Unfortunately, in my experience, guardsman are horrible at getting stuff in their medical records. I had a buddy that was a ANG technician and was all sorts of jacked up due to his military / technician service. Unfortunately for him, he was never told to go over on drill weekend and make sure he saw a air force doctor to talk about what is going on. He had nothing in his medical records so was unable to even go to the VA.
I try to make sure all young guardsmen know how important it is to document anything that happens to you while in a military status.
