I Had Hip Replacement Surgery 3-5-14. After I Did Rehab.

I had hip replacement surgery 3-5-14. after I did rehab. Then Istarted feeling pain on the outside of my hip. I was given a cortisone shot and more rehab. then thesurgeon himself gave me another cortisone shot. this was 1-5-15. I can't sleep on that side because of pain and pressure. it hurts all the time.
what canI do? I have used voltaren gel also.
