I have never broken anything (possible fractured rib right now, though), but have developed plantar fasciitis in my right heel. I ride regular, so I'm mostly fine when I ride. But whenever I try to practice switch, that's when my heel hurts more and more. I can barely walk at the end of the day. Taking my boot off is a bitch, and after a few hours of driving back... I hop walk. It hurts me to walk for a few days. Obviously, it's worth it.
I go running often enough that if I just don't do switch very much, I'm pretty much fine. I also do my old physical therapy exercises from after I had surgery on my ankle. Do you have any physical therapy exercises you can do to help with the pain?
Can you describe more what the pain feels like, and where? If it's similarish, I can share what I do to help.
