Indeed, congratulations on the receipt of your IPEB findings; good deal!
From my experiences while on military active duty and progressing thru the DoD IDES MEB/PEB process, I had a total of two Formal PEB (FPEB) hearings. As such, I already had two "unfit for duty" medical conditions albeit I felt that I had additional medical conditions which should had been considered "unfit for duty" at that particular point in time.
Unfortunately, each FPEB hearing didn't agree with my request for additional "unfit for duty" medical conditions, but at least I remain "positively proactive" and I currently have a clear conscience since I tried via implementing my IDES appeal rights.
In my opinion, if you have medical evidence and/or medical documentation to prove that your back and radiculopathy should be considered "unfit for duty" medical conditions, then by all means request a FPEB hearing. But, be very
cautious when considering a FPEB since upon the start of the FPEB hearing, all previous PEB recommendations become null and void.
As such, the President of the FPEB could decide that your current "unfit for duty" medical condition is now considered a "fit for duty" medical condition; is that feasible in your particular situation? If no, then maybe you should consider requesting a FPEB hearing since the worst case scenario would seem to be receiving the same DoD 70% TDRL recommendation; at least in my opinion.
Bottom line is to please consider all the positive benefits to include the negative benefits of requesting a FPEB hearing at this particular point in time while in the DoD IDES process. Ask yourself, can you handle a potentially unfavorable recommendation by the FPEB at this point?
With that all said, please take care and I hope that you obtain the PEB results you want! Peace!
Thus, I quite often comment that "possessing well-informed knowledge is truly a powerful equalizer!"
Best Wishes!
