Hi:
I saw your post after looking up accessory navicular. I have one in my right foot. I had a similar injury that kept me from going to a wedding in India. My neighbors dog ran into me at night full speed causing me to role my foot inward. Before I knew I had a defect in my right foot but after that injury the bone was much more pronounced. I was suppose to go to Bangalore too.
Did you have surgery on it?
How is it now?
Thanks,
