Pain in the shoulder joint when walking is mainly due to edema and bruising of the anterior biceps and long head tendons, as well as the posterior infraspinatus and teres minor tendons. For example, if there is an injury around the shoulder joint, lifting or carrying heavy objects or external collision, it may lead to local injury, and during the shoulder joint activity, it may cause painful strain on the injury lesion. 2. 3. Adhesions may have formed around the shoulder joint, for example, after the formation of adhesions, during shoulder joint activities, there will be a pull between the tissues and the tissues, which will also cause significant pain. 4. Frozen shoulder is caused by cold in the shoulder joint, because after cold, blood circulation slows down and inflammatory lesions in the shoulder joint accumulate, resulting in significant inflammation and edema. This can also lead to irritation and pain during the activity.
