How long? It varies from patient to patient. I tell my patients 6 weeks but depends on severity of the sprain which you give no information on. Could answer better if new more like did you get treatment x-ray etc...
Depends on. How you are feeling. I would make sure you have a good ankle brace on that foot while excerciseng.
