You should still be ok. After you see the VA docs in July for your C&P exams, the VA doc will complete his/her narrative and send it to your PEBLO/PCM. Your doc will then complete his/her NARSUM, and then the whole package goes back to your local MEB (DAWG). This is where you need to intervene and ensure that your MEB form lists all your conditions that affect your job and are "boardable" before it goes back to the DAWG. Do not sign anything else unless your conditions are accurately listed on the MEB paperwork...if any conditions are omitted, request that they be added to the NARSUM and the MEB form. This might mean that your PCM will have to rewrite them, but this is about you- not them. If you get any push back, you have the right to request an independent medical review (IMR) where an impartial doc will review your records and your MEB paperwork to ensure that everything makes sense. You are also within bounds if you need to seek legal assistance to review everything before you sign it. Hopefully, your PEBLO/PCM will agree that they need to add the Menieres without giving you any flack about it.
All this is pre-IPEB stuff. That's why you want to make sure that everything is correct now (while everything is still local) and before your package leaves your PEBLO to go up to the IPEB.
