Accessory Navicular Syndrome
Q. There is a bump below my ankle bone. Is that a problem?
A.
Far more people have the extra bone with no symptoms. If it began to hurt after being pressed or after a sprain, it is worth checking.
📝 Detailed Answer
An extra bone called the accessory navicular is reported in about 10 to 14% of people. Having it does not mean symptoms will follow.
Check whether any of these apply.
- There is a bump about 2cm forward and below the inner ankle bone
- Wearing shoes that fit the width of the foot snugly makes that spot red or painful
- After spraining the ankle, a pressing pain appeared near the ankle bone
It is generally understood to arise when the bone does not fuse normally from birth.
