Wow, very sorry that happened to you! Are you working with a physical therapist? You need to be. I think one of the things they always talk about is keep moving. Exercise is essential regularly. There are braces that can help if you don't have that yet. Orthotics are helpful. Relaxation things like yoga, meditation can help believe it or not. Working with a physical therapist to improve strength and mobility and regular walking are the things I've really read are most helpful.
