Ankle Bruise. It may be pain from soft tissue damage. Try resting it (for 1-2 weeks), icing, compressing wraps or bracing, and elevating your 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 by a specialist. Hope this was helpful.
Soft tissue injury. The xray only shows if you have a fracture. You could still have a ankle sprain which is a soft tissue injury of the ligaments and tendons. If you are having ongoing pain, you should see your regular doctor.
