You should.
stuff that isn’t bothering you now or an issue at all may get worse later.
establishing that it’s service connected, even if it’s rated at 0%, is a lot easier now than it will be later.
For example…I broke a big toe on AD. Fully healed. Zero issues. But it’s documented and service connected at 0%. If, some time in the future, that joint decides to be the epicenter of arthritis, or fuses up, or starts growing horns…or some other such bullshit … getting it treated will be a lot easier.
same with the neck/back. Fine today. But if I can’t move it in my 60s me and the va May have to chat.
