13 Year old with pain

About 9 months ago, I injured my back while lifting a weight. I used my back instead of my legs, and later that day I was in extreme pain. I tried to keep playing through it, but it was unbearable.

I went to physical therapy and was given stretches to do. I had to take the season off to recover. Even after I healed, the pain would come back whenever I returned to playing. Eventually, I took a month-long break, and the pain went away. After that, I was able to play a full 6-month season with no issues.

But once the season ended, I lifted my backpack with bad form again, and the pain returned. This time it’s not as bad, but it’s still painful. I visited a chiropractor, but it didn’t help much.

Right now, I’m in pain again. The symptoms include: • Sharp pain starting in my right glute and going halfway down my leg • My right glute feels weak • Sometimes I feel pain in my lower back, near the lower vertebrae

I’m not sure what to do anymore. Should I just take another couple weeks off and see if it heals again like last time? I really n do not want it coming back.
