I typically have weak ankles, but 5 days ago i fell down a small step and could hardly walk, very very very sore and still is what's going on?

No broken bones?: If you have a fall and your bones ache, it might be a fracture. Many times we try to walk it off, but maybe something else is going on. One thing about walking on our feet, they never really get a chance to rest and heal!

Ankle sprain: Use a mueller brace with velcro fro 2 months and ucbl orthotics for future control in your shoes every day.
