Dealing with Bladder Cancer Metastasis to Femoral Bones

I was diagnosed with bladder cancer metastasis to my femoral bones that started with extreme pain in my hip and groin to the point where I couldn't even walk with a walker. I did have radiotherapy, chemotherapy and finally had resection of femoral bone tumor by a very good orthopedic oncologist which helped tremendously. after almost six months I am still having some pain to the point that I have to use walker. of course I have been to pain management, physical therapy and all I am still having pain. Luckily my pain doctor suggested that pain pump that was implanted last week which I think is helping. My question is, is there anyone who may have experienced a similar situation. l would highly appreciate any advice. Best regards, Reza
