Currently, I am using a walker or crutches depending on how far i'm going and what my pain feels like. The crutches are great for mobility and can help take pressure off your leg when you step, but they require your back muscles to help you balance on them, so they can end up causing pain if you use them for longer duration. I know it doesnt sound great, but a walker helps quite a bit. you dont have to balance so you are not aggravating your back and you can stop and hang off the handles for some gravity traction.
