Rotator cuff injuries are not directly related to cold weather, but they may be aggravated after exposure to cold. This is because most rotator cuff injuries are caused by indirect violent injuries, such as the palm of the hand bracing against the ground during a fall, or the outside of the arm against an impact. Other causes, such as advanced age, prolonged overuse of the shoulder, and sports injuries, are also more common causes of rotator cuff injuries. When rotator cuff injury occurs, if the shoulder is stimulated by cold, it will affect the blood circulation and aggravate the inflammatory response of the shoulder, which will aggravate the symptoms of rotator cuff injury. To summarize, there is no direct relationship between rotator cuff injury and cold weather. After rotator cuff injury, it will cause shoulder pain and activity limitation. When this phenomenon occurs, you should go to the hospital for further diagnosis and treatment in time to avoid aggravation of the condition.
