What Cause Severe Pain In Hip After A Surgery For Torn Labrum?

Hi I had hip surgery for a torn labrum 6 months ago. Since then I stick through out the day, with great pain from my hip to my just above my knee. Leaving me unable to move for about 3-5 min until what feels pops out or gets stuck goes back. As soon as it does the pain is totally gone. My Dr.has no idea. What do you think?
