First time, I sprained my ankle was about 10 years ago playing volleyball. Couldn't put any weight on it for a few days. After about 3 weeks, I could play again with a brace but couldn't do much jumping. After about 6 weeks, I was almost back to normal. After a year or so, I stopped noticing the tightness.
Second time I sprained my ankle was a few months ago. After about a week, I could walk on it, but it was still painful. After 4 weeks, I went to Disneyland and was able to walk around all day, but it was pretty sore afterwards. After about 7 weeks, I started playing volleyball again and it's been ok since then. Now it's been 15 weeks, and i'm pretty much full strength, but it's still not completely healed yet. On a regular basis, I'll step on it funny and feel a little twinge of pain. And it still feels pretty tight.
