I have a question regarding getting an appeal approved for sleep apnea now that I am out of the military. While I was active duty, I was given two sleep studies that did not show enough apnea for a diagnosis. I also had throat implants and a sinus surgery to help with breathing, fatigue from poor sleep, and snoring. Nothing seemed to help. I did get a service connection for sinusitis with zero compensation. Last month my doctor sent me to another sleep study which revealed sleep apnea and then I followed up with another test using the CPAP. Now I'm wanting to go back to the VA and submit a claim and I'm wondering if there is any advice on what to do. I am having my doctor look at my service medical records to see what is in there. Thanks for any advice you folks have.
