Walk every morning. Walk every hour (unless sleeping). Walk uphill every day (see documentary on Blue Zones).
But for now: just focus on resisting the urge to tell me why it can’t be done… Like Nike’s slogan: “Just do it”
Good luck, it’s though, and painful but it gets better.
With my husband (and probably most people who already already suffering with pain) the pain was too much to walk, and walking was very much counterproductive, so this is bad advise, especially the l "focus on resisting the urge to tell me why it can’t be done" part. It's not the type of pain that you can just power through. He said the pain caused his legs to physically stop working. He had to do PT exercises first and build up to walking.
