File the NOD (notice of disagreement). You don't need to elaborate on the reasons why you disagree when you file it. You just need to list each of the contentions, the decisions of which you disagree. Example: Tendinitis, PTSD, etc...  There will still be plenty of time to gather evidence while waiting for your appeal to be adjudicated. I would elect DRO review if I were you. If the DRO does not find in your favor, you can still appeal to the BVA. Each of these stages will take a long time and give you plenty of time to gather and submit evidence, which you can do at any time during the appeals process.
