I injured my knee in the DMZ South Korea, I have constant pain in my knee for the last 50 years it does swell up occasionally never gave it any thought is this available for VA care. My brother told me it should be covered.
Aren't you enrolled for VA care? If not, you should be. Register here https://www.va.gov/health-care/ If you're eligible you'll have an appointment with a primary caregiver and you can talk about that knee then. Good luck.
