Which is the correct breakdown of the medical term metatarsalgia into its component parts?

I think the correct breakdown would be meta/tarsal/algia = before/tarsal/pain.

Metatarsalgia is a painful condition that affects the ball of the foot. The metatarsals are bones that connect the toes to the ankles. It may result from overuse or high impact sports, arthritis, and wearing inappropriate footwear, as high heeled shoes. The ball of the foot becomes painful and inflamed.
