Persistent and severe shoulder pain, often due to dislocation of the shoulder joint. There is a clear history of trauma. Traumatic anterior shoulder dislocation has a clear history of trauma, pain, swelling and dysfunction of the shoulder. The injured limb is flexibly fixed in a mildly abducted internal rotation position with the elbow flexed and the affected forearm supported by the healthy hand. What are the prevention methods for persistent and severe shoulder pain? 1.When there is persistent and severe shoulder pain, you should seek medical attention as soon as possible. Patients should pay attention to rehabilitation exercises after repositioning treatment. 2.A reasonable diet with high fiber and fresh vegetables and fruits, balanced nutrition, including protein, sugar, fat, vitamins, trace elements and dietary fiber and other essential nutrients, meat and vegetables, diversification of food varieties, giving full play to the complementary role of nutrients between foods, is also very helpful in the prevention of this disease. 3, fully prepared activities. The whole body activities 5-6 minutes, such as running, unarmed exercise, targeted special exercises: do a few sections of the upper body and upper limbs of dumbbell exercises (such as chest expansion, side planks, shoulder rings, etc.), or use light equipment to do 2 – 3 sets of bench press, arm curls and other exercises, so that the muscles, ligaments and other tissues to achieve a certain “heat”, so that the operation of the joints flexible up. 4, the action range should not be too large. As we all know, the squat amplitude is too large easy to make the knee joint injury. Similarly, the shoulder joint movement amplitude is too large, too hard, will also make the joint around the tissue injury. For example, when doing the supine bird, the arms should not be lower than the torso: to do the bench press, in order to slow the pressure of the shoulder, tension, push up should not “lock the shoulder”, bend the elbow when the shoulder gluteal bone can not be forward, to try to rely on the contraction of the pectoralis major, latissimus dorsi to complete the action.
