I am sure this has been addressed somewhere, but I could not find it on the board. I retired about 5 years ago w/close to 22 years active duty (USN), currently 46 years old. I was an Aviation Electronics Tech and worked on A/C. When discharged I received no disability rating. My hearing stinks and is declining and I believe that Aircraft noise is a factor. I also have some issue w/pain in my elbow that was addressed once very early on in my career and has now returned. What steps do I need to take see if I can get a disability rating? I want to get it right the first time through. I was never a sick bay commando, so my medical file is rather thin and I am not very versed on how I should approach this. I assume I will have to do one of these "C&P" exams. Please advise if this post should be somewhere else. Thanks in advance!
