I had hip surgery because of a fall and had total hip replacement in February. All went well. After rehab for 7 days I went to outside rehab for 2 months. I was doing well there and now I am experiencing knee pain and hip pain especially when I walk. I m limping and now my other leg feels sore and difficult to lift. I m doling exercises as I was in rehab and also going to a gym and using the bicycle for 20 minutes. My lower back is hurting also and when I sit more than 15 minutes I cannot just get up and walk. I have to almost stand for almost a minute before I can move forward. I don t use a cane. I m 83 years old, and had knee replacement 11 years ago on same leg as hip replacement.
