I know my ankle is not sprained but my ankle feels really weak.. i don't remember hurting my self. what can i do ? do i need x rays? do i stop soccer

Let me try to help: You said you play soccer which applies high demand on your ankle. Two explanations i could offer you. 1-injury to the ankle has not recovered totally. 2-osteochondreal injury to the ankle bone will not show on the x-ray, need MRI to show. Go to orthopedic surgeon with ankle specialty he will be able to help you. Good luck.

See below: It would be helpful to rest it and use a compression wrap. If no injury you should not need and x-ray. If continues see a podiatrist.

Have it evaluated: If you continue to have weakness or instability have it evaluated.
