1. Adjust the exercise mode: If the knee pain is caused by improper exercise mode, then you need to adjust the exercise mode. For example, if you feel knee pain during running, you can try to reduce the intensity and frequency of running, or change to low-impact sports such as walking or swimming.

2, take cold and hot therapy: cold and hot therapy helps to relieve the symptoms of knee pain. For example, applying an ice pack to the painful part, or applying a hot water bag or a hot towel to the painful part can relieve the pain.

3, consider medication: If the knee pain is very serious, you need to consider using medication. For example, over-the-counter drugs such as ibuprofen can be used to relieve pain and inflammation. However, if the knee pain continues to be severe, it is recommended to seek medical attention immediately.
