What's the #1 Homeopathic Remedy for Joint Pain & Stiffness?

If you were thinking Arnica montana, you would be close, but not correct!  While Arnica is considered the number one homeopathic remedy for pain, it's primary keynotes are "muscle soreness" and "over-exertion".  Another answer we saw a few times when we posted this question on our facebook page was Ruta grav, but this homeopathic remedy is more closely aligned with joint "injuires".
