My niece developed pain in her ankle, in the top in front. It hurts most when she sits and points her toes towards her body, for example. The doctor said it was due to something getting pinched and that it was caused by her dancing. What is that and how is it fixed?
While it's not possible to tell what exactly is wrong with your niece's foot without examining it, it does sound like it may be a case of anterior ankle impingement. This is, simply, what you said - something, in this case soft tissues in the ankle, have been caught in the ankle joint and cause pain whenever she moves her toes upwards, reducing the angle of the ankle. Treatment for ankle impingement may involved rest and bracing, or it may involve surgery.
