A couple of years ago, I twisted my ankle severely enough to warrant a trek to the doctor's office, where he promptly put me on crutches and a six-week stay-off-the-foot regimen.
I learned then that doctors have a scale to rate twisted ankles as to degree of severity. That you are unable to walk from one side of the house to the other without bringing on pain would probably come out on the scale as a more serious strain. And a doctor would likely recommend you stay off your foot until you can make that trek without pain of any kind.
Here's hoping for the best for you. But you might want to consider going to the doctor if this pain persists. And do be realistic about the need to allow complete healing before you start your runs again. Better to take a bit longer to heal than to worsen the problem, right?
Best of success to you.
