Leg Pain Diagnosis Leg Pain?

Leg pain? - leg pain diagnosis

I do a lot of ballet, and it is never a problem. But in gym class, I still have pain in the leg after a somersault.

The pain is when the left leg meets the hip, and somehow I felt as if it was the separation of the connector, so you feel better. But that would be obvious that to make it worse. It hurts when I expense of approximately 15 minutes on foot, but when he feels well again.

This happens when I do a somersault is really annoying to me.

Who knows what it is or how to avoid it?

Thank you!
