My medical board starts April 1. Background: I had surgery a year ago, to help with my hearing and to remove a tumor. Since the surgery I have a loss balance and attacks of dizziness lasting anywhere from about 30min to an hour and half before the medications I have to take knock me out. I have been diagnosed with Meniere's Disease (currently no cure). I am a BM, obviously the CG didn't think it was a good idea for me to be driving boats or shoot guns, so I have been driving a desk ever since. In an effort to help me out, my command at a station and the co-located sector decided I could work as a SAR Controller/OUC. After the "C" school, within 2 months I certifed, and I was PCS'd as part of the whole TLD process. Although, I want to make sure I didn't set myself up for an admin sep. Meniere's disease is rated anywhere from 30-100% and will be a long road for me. So, I have been front-loading myself about the MED board process. In the PEB they determine if I can do my job and base it off of office, grade, rating, etc.; so, I can do my current job...yes because I am sitting in a chair for most of it...but, I ended up here because I could not do my job as a BM. I will never be able to underway on boats/cutters because of the unpredicatbleness of the disease. I would appreciate any feedback anyone may have to offer...thank you in advance.
