Shoulder pain occurs in cold weather, especially in patients with frozen shoulder, because the onset of frozen shoulder can easily lead to adhesion contracture of the ligaments and joint capsule around the shoulder joint, thus causing pain in the shoulder, especially when the weather changes or when cold air is encountered, causing pain in the shoulder to increase significantly. Secondly, it can be seen in middle-aged and elderly people who have degeneration and osteophytes in the shoulder joint. The enlarged bone can easily stimulate the surrounding ligaments and joint capsule to develop edema, which can lead to spastic contraction of the ligaments and joint capsule after cold, thus causing obvious pain in the shoulder joint. Thirdly, it is seen that the soft tissues in the shoulder joint are not recovering well after the injury, which causes the soft tissues to be in a semi-edematous state, and they are particularly sensitive to the stimulation of cold wind, causing shoulder pain.
