The gonadal reflex zone is located on the bottom of the foot. The causes of pain on the bottom of the foot when pressed are many, such as fasciitis of the foot, Achilles tendonitis, osteophytes of the heel bone, and pain caused by lesions in the local part of the genital reflex zone, which cannot be diagnosed as genitourinary gland disease, but can only be used as a reference. If there are other accompanying symptoms, the diagnosis can be made in conjunction with the genitourinary system examination. Soak your feet in hot water at night before going to bed to promote local blood circulation. When the pain is more obvious, it is recommended to go to orthopedic surgery for examination.
