I also often play basketball to exercise. Playing basketball is a combination of aerobic exercise and anaerobic exercise. When it is intense, it is strenuous exercise. Excessive exercise consumes health. You are in the growing period, you said to play for two or three hours, and my muscles ache after playing for a long time. My knee hurts every time I finish playing, indicating excessive exercise. For your knee, it is the exercise load that will cause knee pain.

How to maintain, and ease?

1, reduce your strenuous exercise time.

2, you said that you often walk in Europe, which is the kind that needs to jump, and taking off and landing too much is also a kind of injury to your knees. Reduce the number of jumps.

3. If you have time, you can pay attention to some sports maintenance knowledge. In fact, posture during exercise is very important. Your incorrect posture will do harm to some parts of your body.

4. Warm up before exercise and bring knee pads.

Basketball is very interesting and I like it very much, but I suggest that time should be controlled. I wish you better and better skills?
