Have you ever had bunion surgery? It can be a long rehabilitation process. Often people shift the weight onto the second toe when walking after bunion surgery, instead of putting full weight down onto the big toe right before pushing off. The patient has been walking this way for a very long time, and now shifting the way one walks is pretty hard.
Part of the problem is that people who have bunion surgery developed a bunion partly due to having too much pronation (flat feet). If you have flat feet, your arch will get too stretched out and you will push off your second toe instead of your first toe. Even after the bunion surgery you might continue to push off your second toe–and that will be aggravating. What exercise can you do to strengthen your foot to reduce flat foot and prepare for a bunion surgery?
While you are sitting you can raise you feet up like are coming up on your tip toes. That will start to strengthen the arch, and give your big toe better range of motion.
You will also need scar tissue mobilization to help the big toe be able to bend down and up as you walk.
Good luck with your bunion surgery!
