(Question) How should knee pain be treated?

Since about a year ago, I have been experiencing intermittent pain in my right knee. Usually, it doesn't hurt when I walk. The pain occurs suddenly when I lift something heavy or carry a heavy bag, or if my posture is slightly off. Sometimes it feels dull and aching in certain situations, but it's fine most of the time. I'm still young, so I'm not worried about knee joint issues, which is a bit confusing. Will visiting an orthopedic surgeon completely cure the knee pain? Or would taking supplements that might help improve the condition be beneficial?
