Black3018,
I have OSA and it's not SC. I am still fighting and have been since 2004. I retired 2001. I have all the diagnoses of OSA but never got diagnosed while on AD, although my wife told me to and my Army buddies did too, but I blew it off and thought nothing of it; I am regretting that to this day. Yes, I'm getting treatment from VA and they provide me all the medical support I need, but WON'T SC. I did the friend and wife letters too, but still denied. I am also diagnosed with PTSD with mood disorder, sleep disturbance, depression, etc...etc. Still not SC for SA.
I hate to put salt in your wound but Buck is 100. If you don't have anything in your records while you were in service for SA you are going up a hill with a 500lb ruck. Not saying you are defeated, but saying it's going to be a little more challenging than you think. We love a challenge... huh?
I highly recommend before putting an OSA claim in you find something in your medical files that can be SC to OSA...example TBI (highly possible). You might try Fibromyalgia. Fibro is connected to sleep disturbance. But even that's not saying much.
Short story: I had a friend who put a claim in for SA and got denied over and over again but kept on fighting for over 15 years. He got his claim approved after researching his medical records very...very...Very...closely and found one statement where a doctor recommend he get a sleep test. That was enough and all he needed. You know the rest of the story.
It's not about your illness, although that is important to get treatment...it's about being SC....saying that to mean this; Get your records in order by date, after that, request a C&P, take all researched records to C&P highlighting the areas pertaining to the claim so there will be no misunderstandings of proof; remember C&P doc's are not looking for conversation only proof on paper. Key thought "You don't have to say anything as long as it's documented...trust me.
True story: I did a C&P and the doctor found something in my medical records I never thought of claiming but complained about since 1984...headache's. These headache's manifested into migraines from that time to present. Just think, I've been complaining about headache's since 1984 but between 84 and present they grew into migraines and I thought it was because of OSA. I do have OSA but now I have found out that my headache's now migraines, resulted from my OSA. I don't know which way to go with this but I am sure within one year I'll figure it OUT!
Sorry for being long winded
