So as hopeless as my original post was, Ive obtained both my MEPS and flight physicals. I ended up being broken until proven healthy. I went back to the VA and asked to be re-evaluated, got an MRI, got reduced from 10% to 0% for my back, saw a civilian neurologist, saw physical therapist, got written approval from both and then explained my situation to MEPS and the flight surgeon.
I will say be careful what medical documenation you share with MEPS. Im not saying hide legitimate medical issues, but dont make more work for yourself and MEPS than you have to. My initial recruiter told me because I had a service connected disability rating, that Id have to produce all military medical records for MEPS (another recruiter down the road later told me sharing any of this information was unnecessary). Not only was this a very lengthy process to get the documents from the VA, it raised a lot of questions.
For example, I once was given Motrin for some achey knees and during the busy the doc noted that Im now-legged. Thats it. No follow up. Did another 4 years in the army without a single complaint about my knees. But, because MEPS saw this I had to get X-rays and a note from an orthopedic doctor saying theyd be okay in the army.
Ill also say that if you are prior service, it may be cheaper to go through the VA for these notes or imaging, but consider time saved by going to civilian doctors.
There is a good podcast that describes the process of MEPS medical waivers. There are a couple other episodes that might be helpful other people too.
Some stuff isnt and shouldnt be waiverable, but just because youre told no the first time doesnt mean all hope is necessarily lost.
