1 month in on recovery of sprained ankle. Did some exercises for ankle yesterday and swelling came back with slight pain. What does this mean?

Rest. 4 weeks may not be enough time for complete healing before starting therapy. 6-8 wks is typically the amount of time it takes to heal a sprain if immobilized. Even with complete healing, scar tissue develops and can contribute to swelling on and off for months during rehab. Check with your physician in person for proper rehabilitation! .
