I would go see an orthopedic doctor. That is what I did. I was getting sharp pain in my ankles when walking. I tried steroid shots, bracing, ice. Finally they did an mri and found out that I had torn a ligament. I had surgery last week and am laid up for 6 weeks non weightbearing in a cast. It sucks. Hopefully yours won't be what I have but go get it checked out. I don't still know how I injured it.
