ECHOES, I would guess the length of time you are laid up would vary depending on the severity of the injury and its cause. Is it acute, chronic, degenerative, etc.? I have heard that sometimes people wear a brace or cast for a while to help provide support and give the ankle a rest.
Is there any way you can see a regular orthopod for the injury instead of the urgent care clinic? You may get more detailed and relevant advice from a specialist.
Sorry you are hurting.
