running again

Hi

It has been over year and a half from my hip replacement, on my right hip.  I had  physical therapy, but I have a dent where scar is.  At first I didn’t see a difference just a thin scar, but I must have been swollen because after about a year I noticed the dent.  I told my surgeon, he sent me went to physical therapy.  I was told the muscles in the one side were shrinking and I had to build them back. I am back in therapy to build back the strength and muscle.  When I run I can feel the right leg doesn’t move as well as my left side.  I would like to run again, but don’t know how to be begin, should I just start running as best I can?  Physical therapist said I should run, so I can’t ask her how start out, without hurting myself.  Any suggestions.
