1. Muscle relaxation: Use self-massage tools such as roller massager or yoga ball to relax and massage the muscles around the clavicle, especially the tense shoulders, neck and upper back.

2. Muscle training: Strengthen the muscle balance of the body through fitness training or targeted gymnastics, especially the muscles on the weak side of the body. You can choose shoulder training such as dumbbell side lifting and one-arm dumbbell pressing to strengthen muscle balance.

3. Adjust the sleeping position: Adjust the height of the mattress to a suitable height when sleeping, so that the body lies flat on the bed, and be careful not to press the high shoulders, so as not to aggravate the muscle imbalance.

4. Adjust posture: In daily life, pay attention to maintaining a good sitting posture and standing posture, relax your shoulders naturally, and don't forcibly adjust posture to avoid aggravating muscle imbalance.

5. Seek professional help: If the above methods can't solve the problem, you can consult a physical therapist or a professional fitness coach to learn more targeted muscle balance training methods to help correct posture problems.

It should be noted that the problem of muscle imbalance requires long-term training and adjustment, patience and persistence. In muscle training, we should avoid overtraining or incorrect training posture, so as not to cause muscle injury or aggravate the imbalance problem.
