I am in sports and my hip hurts when standing and sitting and after walking around. While wAlking my hip clicks what do I do?

Seek professional medical assistance.

Read about synovial fluid, which protects many joints in the body, and which leaks out at times. That's just ONE possibility.
And see if you can find a good orthopedist or sports med doc.

Synovial joint - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Synovial_joint)

See a doctor. Better to go and find out it's nothing to worry about, than wait and find out it was.
