Does knee pain have a neurological origin?

Not usually: Knee pain can be associatyed with low back pain.

Yes and no!: Depends on what is on your mind or what the doctors have told you. Pain is noxious a neurological signal. Most times knee pain is from the muscles that support the "shock absorber"; the foot, knee, hip and si joints complex. See my other answers and get a sense of how you can treat yourself. Don't get distracted by the small stuff on scans and xrays, because you can’t see pain that way.
