Okay, so it sounds like you may be reserve??? You mentioned 21 total guard. I’m not that knowledgeable when it comes to reserve, but there are other regulars on here that can chime in when it comes to your situation.
My advice would be you have to do what’s best for YOU!!! when it comes to medical most of the times that takes a toll and in my eyes your health comes first.
If you want to fight it and think you can! Then by all means go for it!! There are a couple of attorneys on this forum. But that comes at a price!!! But that’s what they live/breathe and are the subject matter aspect. I can give you there contact info in a separate message.
I could go on and on but don’t want you reading for days.
I am just trying to be an advocate for others, share my story, experience and offer advice.
Currently going on 4 months into my MEDBOARD, and my case was just forwarded up to the PEB.
Feel free to hit me up.
All the best
