What treatment did Sakuragi receive at the end of Slam Dunk?

Sakuragi's injuries should be acute lumbar muscle sprain and hard joint sprain, because if you look closely at the comics, you will find that Sakuragi hit his back many times. In other words, Sakuragi's back should have been invisible before, but it finally broke out after that heavy fall. Because I was injured like this, and I fell out when I flew to save the ball. Like Sakuragi, I almost couldn't stand up at that time, which was very, very painful. After ten days, Sakuragi can sit down, which means that she will recover soon. In my condition, I can't sit normally for twelve days. Therefore, Sakuragi's injury is not only the same as mine, but also similar in severity. And the doctor told me that I can't do strenuous exercise for about half a year. Therefore, Sakuragi probably won't be able to compete normally until the second year of high school.
