Welcome to the site. In the resource section of this website you can find your services' guidance on unfitting conditions. You may want to compare your known conditions against the service guidance. It is important to remember that an MEB does not mean you will be separated or retired. Some MEBs result in return to duty (RTD) or RTD with restrictions.
So it sounds like Spondylosis is the cause for concern. However I have scored a 94% on my last 3 fitness exams and the most recent being with out a profile. I have requested my PCM RTD. I have never not been able to deploy and have 6+ times. Seems the MEB was lost in the system and I feel it's not needed.
