Long post ahead. So my package was just submitted and now I am waiting for a decision to be made whether I will be retained in the Air Force or not. I was diagnosed with Chiari Malformation and Chiari Malformation type 1 (not sure if there is a difference) as well as Syringomyelia and syringobulbia (spinal syrinx, fluid filled spinal cyst essentially). I have had multiple MRIs that have confirmed the diagnosis but my neurosurgeon stated that he doesn't think the chiari was caused by my military service but doing the job everyday could cause my symptoms to get worse. I have opted to not get the surgery despite the recommendation from my neurosurgeon. So, my question is, has anyone had a similar diagnosis and if so what was your rating and process like? From my understanding the military considers the chiari a congenital defect and therefore does not consider it rateable. I have a laundry list of other things that I'm assuming could get me a higher rating with the VA. Hearing loss should be added here soon and have a sleep study scheduled for January. Any advice on what to do from here, anything I should particularly be on the lookout for, questions I should be asking? Already documenting everything I can and keeping records of every appt I go to. Is there a difference between medically separated and medically retired, will I keep tricare, how does the VA rating system work and will I get a rating? Sorry for the long winded post, just trying to do my research and get ahead of this. Thanks for any responses.
