Hi...
If I were your treating doctor then..
I would like to know the details of
injury sustained..in detail..
as of now with details available with me..
I would suggest you to ice up the injured area...
keep it compressed with a compression bandage..
keep icing your calf muscles ...if possible slowly knead her calf muscle so that it help her in relieving spasm and associated
stiffness which be a indirect cause of her
knee pain...
Don't hang your foot keep it elevated...from foot to mid thigh...with a pilow...
Take it easy on your activities don't try to bear weight and keep attempting movement to check if it is painful.
once these episode gets over..and heal completely I suggest you to have a good ankle& glute rehab program... balance and proprioceptive program for 6 weeks...
Hope this is helpful for you..
Kindly revert back incase you need further clarification....
