Moderately Sharp Pain In Left Hip, Hurting Mainly When I

Moderately sharp pain in left hip, hurting mainly when I exercise, hurting a little less when I walk, not hurting when I stand or sit. Related: about 2-3 days before the pain appeared I had a pretty strong onset of pain across the lower back. It set in pretty quickly; it lasted for about 1 1/2 days and gradually disappeared. Then within another day, the pain started in the hip. After about 1 week the pain disappeared in the hip and has not returned.
