DS is at uni and plays basketball at high level. He sprained his ankle badly 2 weeks ago - it was swollen and he was on crutches for a few days. No breaks. He's seen the university physio once. He's quite independent so is brushing off my questions about what the physio said. He has an ankle brace.and told me he is now back at training and playing in matches. Is this an unusually short recovery time after a sprain? (I know that's up to him, but I want to know if I should worry or not).
