Hope you can get back to a rehab center quickly so you can have the advantages of good PT therapists. Sounds like you got a bad one the first time, have someone do some checking for you. I know when my wife had her first hip replacement the rehab center was not so hot even though the PT personnel were good, she could only stand the place for about three days. For her other hip replacement she went to a different center and it was like night and day.....good food, friendly staff, good accommodations, etc. So have somebody check the rehab locations out and get yourself into a good one ASAP.
