The tear in my L4/5 disc occurred as a result of the MATV I was driving in Afghanistan providing over watch for a convoy, rolling down a hill after the ground gave way. I was knocked unconscious from slamming the left side of my head into the bullet proof glass as we tumbled down the hill, but only briefly, or so I am told. Our HMC corroborates this injury, as well as the physical work up I did upon returning from this deployment. However, my headaches, add, sleep issues did not occur until several years later. How do I tie all or any of these together under CRSC? Still active rn, but will likely be on a MEB before May as my back as not improved, its getting worse - even after a L4/5 fusion - my headaches/migraines require a prescription that's over $100 a pill and require sleep med and CPAP...lol im a mess.
