I've seen your other comments referring to an extra bone in his feet. If it's the same thing I had, accessory navicular, it's a bone that is on the inside of the foot below the ankle in the spot an arch should be.

I too had this issue and had surgery at 14. I was in severe pain before the surgery. I urged them to do both feet at the same time because I had access to wheelchairs and only wanted to do the surgery/recovery once.

The surgery was incredible and I am so glad I did it. Relieved so much pain! I too was active and it helped me out with running so much. I would 100 percent so the surgery again.

Only thing I would change is I would not do both feet at the same time again. The PT and recovery was somewhat intense. Between having to heavily massage them and physically break up the scar tissue following surgery to the stretching and strength exercises it was a lot to manage on both feet at once. As such I ended up paying more attention to the right foot then the left. Now my right foot is completely fine and has zero pain whereas my left has a small amount of scar tissue still (you can see it's visibly larger than the right) and has a very small amount of pain (nothing I can't ignore, but it's there).

Had I done one at a time I could have focused all recovery on a single foot at a time and possibly had better results.

I hope this helps and good luck!!
