I am new to the site. I was recently denied service connection for AS because it was diagnosed 5 years after discharge. I served in the Marine Corps and developed iritis while deployed in Iraq and also have X-ray reports showing sacroiliitis a few months after discharge. I have had multiple joint problems since service. I did receive the anthrax series. I am going to appeal the decision but was hoping I could gather some advice or opinions regarding the denial. I understand arthritis has a presumptive period of 1 year after discharge. I am unclear why I was denied with in service and presumptive period evidence. My VA examiner only commented on my spine and did not address eye involvement or link any other joint pain to the disease. Anyone have any advice for my appeal?
