My commander had me removed from the promotion list?

my commander had me removed from the by name promotion list. long story short he tried to put me back on in feb but HRC said that I have to go to the promotion board. again to filter through all the background info, he had no clue removing me would mean I would have to go the promotion boar. due to medical issues i cannot go to the promotion bard and pretty much all of my chain of command is aware of this issue. my SGM is getting my COL involved now who is pretty up to date on everything except for the fact that I have to go to the promotion bard. my commander , i guess, fells pretty crappy for what he has done and called hrc to see if he could get me back on the promotion list but hrc said again i have to go to the promotion board. what can my COL do to resolve this, will hrc listen to him because he is a COL or am i pretty much screwed?
