Shoulder joint popping can be carried out shoulder muscle relaxation training, muscle strength training and so on. The causes of shoulder popping are related to abnormal development of the shoulder joint, abnormal soft tissues around the shoulder joint, and bony lesions of the shoulder joint, etc. The main cause of shoulder popping is the abnormal friction between the thoracic and scapular junctions. It is mainly due to the abnormal friction between the thorax and the scapula when the scapula is moving, which produces an audible sound or vibration to the touch. If the popping sound is only occasional, it can be observed regularly. If it occurs frequently or is accompanied by soreness or discomfort, it requires medical treatment. Muscle relaxation exercises around the shoulder: Muscle relaxation exercises can be performed in the presence of soft tissue abnormalities around the shoulder joint, such as shoulder impingement. A fascia ball is placed around the shoulder, pressed firmly and rolled diagonally upwards along the shoulder. Muscle strength training: For people with shoulder joint developmental abnormalities, such as the common winged shoulder, which may be related to the lack of muscle strength of the serratus anterior muscle, anterior serratus muscle strength training can be carried out, such as holding a dumbbell in one hand, tilting the upper body to the side that doesn’t hold the dumbbell, and then pushing the dumbbell upwards directly. In addition, if there is pain, inflammation, or degeneration of the shoulder joint, it can be treated with physical therapy (e.g., ultrashort wave, shock wave, etc.), medication (e.g., ibuprofen, diclofenac, etc.), local injections, or surgery. There are many reasons for shoulder joint popping, it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy.
