Endocrine glands and hormones in the human body can cope with the active state of the body and the external temperature, and have the regulation function of making the body run smoothly. During menopause, the secretion of sex hormones decreases or even stops, and many changes take place in the body. In addition to shoulder stiffness and headache, there are symptoms such as dizziness and cold hands and feet.
