I have a sprained ankle. how long is it going to take for it to heal?

Severity.: Well, healing times vary. It's really dependent on the severity of the sprain. Mild, moderate and severe, you might say. You could be up and about with a mild sprain in a minute or two, although the "healing" could take several days. A severe sprain could take immobilization, surgery and months of post sprain care until totally "healed".

That would depend: On how bad the sprain is and what you do for it.....
