I Have Been Told To Take Celebrex For My Knee

I have been told to take celebrex for my knee pain. I have knee replacement on the right knee
and a broken hip on that side also. I fell on it and the orthopaedic doctor said that everything is in place but

I have a bone contusion that will take a long while to heal. xrays show all is in place, but I have pain.
