I rolled my ankle2 weeks ago, and when i walk the botto of myfoot hurts, like this ripping feeling everytime i put pressure on it.no bruise or swelling?

Ligament: You could have torn a ligament or hurt the fibrous lining of the bottom of your foot. See an orthopedist or podiatrist soon.

Sprain: Sounds like a sprained ankle. Try resting it (for 1-2 weeks), icing, compressing wraps or bracing, and elevating your rolled ankle. Take otc antiinflammatory drugs like advil (ibuprofen) or Motrin as directed by the manufacturer to help. If clicking or feeling of ripping or instability continues, get it checked out. Hope this was helpful, if so please vote for me. Thanks!
