hard knot of outer part of foot


both of my twin 12 yrold daughters have knots or nodules on the outer sides of their foot, the knot feels like bone, they say it isn’t painful, just annoying, what could this be? my oldest daughter doesn’t have this and she is 21 and no one else in the extended family has this problem.
Like I said they are both twelve and wear 7 1/2 and 8 1/2 size shoes, Last August they both were in 4-5’s and at the end of this school year they were the 7-8’s.
They have had these “knots” for the past 2 or 3 years.


  1. Without seeing their feet, I can not say for sure. You might be describing the base or tuberosity of the 5th metatarsal. It appears more prominent in some people.

    • That is the normal name of that part of the 5th metatarsal. It may be more prominent in some people than others. But since I can not really see this, I can not say for sure.For your peace of mind, I recommend you have a podiatrist or orthopedist check this out.
