Hi travelsafar I am in the same boat as you unfortunately , a knackered spine with osteoarthritis. It’s 4+ months since my hip replacement , hip is great but back pain persists .Both physio and osteopath say strengthening the core muscles and back muscles will help . Also that your body is realigning to your new hip - like me you probably walked with a lean prior to op, I did get a bit lax about exercises before my hip op as everything was so painful and difficult . Swimming has helped a lot and would recommend it . I’m intending to find beginners classes for Tai Chi in September to try and improve my appalling balance, and hopefully rejoin a Pilates class but so far all local classes are full ?. The Osteopath manipulated my feet yesterday , he said I was walking like a penguin! They certainly feel better today ..
