Army MEB at 17yrs

Just hit 17 years active duty and I recently got an MRI for my back. They said I have three mild herniated discs. My PCM said that it isn’t likely that pain management would “take on” my case and I didn’t respond to PT. When I asked what the next COA would be, he said he was looking at recommending for MEB. I thought it was kind of extreme as I can still pass a PT test well above minimum requirements and the pain doesn’t stop me from performing my duties. At the same time, I just got some Lab results and from a quick search, it looks like I may have Celiac Disease. I am just wondering now if these two together are going to for sure initiate an MEB, or if there is a chance to make it to 20. I’ve seen some people post about COAD, but it seemed like most approved were at 18+ years already.

Any insight or recommendations are appreciated.
