Board reasoning
The Board found the right arm inflammation preexisted service and was not aggravated by service. It relied on multiple medical opinions stating no nexus to service and treating preexisting condition as a symptom rather than a disease, and noted no chronicity during or after service. Lay statements were considered but not given weight as to medical causation per Jandreau and Layno.
