I don't know you, and know nothing of your plight with back and knee pain. Please don't take this as trying to trivialize what must be a very difficult condition. That being said, it's really amazing what can be done with your body that minimizes stress on the parts that are injured. You might be able to do yoga and strengthen your stomach and back muscles to take loading off your spine. Running will always be difficult if you have injured your knees, but cycling might still be an option. Will this fix the core issue and make the pain go away? Not at all. Particularly the knees; there's no getting around them when trying to walk. However, they might allow you to build strength in muscles that might compensate a little for the issues you have.
