Symptoms 10, two yīn

Below is a brief description of the major two yīn symptoms, with links to entries that provide more detail. See also diseases of the two yīn: retracted scrotum; genital damp-itch; mounting; foxlike mounting; cold mounting; water mounting; prolapse of the uterus; anal welling-abscess; anal fistula; hemorrhoids; and prolapse of the rectum.

Painful swollen testicles (睾丸肿痛 gāo wán zhǒng tòng): Painful swollen testicles with redness of the scrotum is a sign of liver-gallbladder damp-heat pouring downward.

Swelling of the scrotum (阴囊肿大 yīn náng zhǒng dà): Swelling of the scrotum without redness or itching may indicate yīn swelling, water mounting, or foxlike mounting.

Yīn swelling (阴肿 yīn zhǒng) of the scrotum is a local manifestation of severe generalized water swelling. This is easily distinguished from the following types of swelling of the scrotum by the presence of water swelling in other parts of the body.

Water mounting (水疝 shuǐ shàn), corresponding to scrotal hydrocele in biomedicine, is a swollen scrotum that feels full of water and appears orange and translucent under a light transmission test. In the light transmission test, a sheet of non-translucent paper is rolled into a tube, and one end of it is pressed against one side of the scrotum. When a flashlight is pressed against the other side of the scrotum, the amount of light appearing in the paper tube indicates the degree of translucence of the scrotum. In water mounting, the paper tube shows an orange light, indicating a high degree of translucence. It is attributed to water-damp pouring downward or to contraction of wind, cold, or damp evils.

Foxlike mounting (狐疝 hú shàn), also called mounting qì (疝气 shàn qì), corresponding to inguinal hernia in biomedicine, is a soft swelling of the scrotum that disappears when the patient lies flat. Unlike water mounting, the light transmission test reveals no translucence. Foxlike mounting is caused by the small intestine descending into the scrotum when the patient stands and retracting when the patient lies flat. It is attributable to liver depression, cold-damp, damp-heat, qì vacuity, or prolonged standing or walking.

Retracted scrotum (阴囊收缩 yīn náng shōu suō): Shrinking of the contents of the scrotum and partial withdrawal into the abdominal cavity. It occurs in cold stagnating in the liver vessel and in other cold patterns such as yáng desertion. It can also occur when yáng brightness (yáng míng) (yáng míng) heat enters the reverting yīn (jué yīn) (jué yīn) channel.

Scrotal itch (阴囊瘙痒 yīn náng sào yǎng): Itching of the scrotum, often associated with redness, burning sensation, or scaling indicates scrotal eczema as diagnosed in biomedicine.

Dampness and itching of the genitals (阴部湿痒 yīn bù shī yǎng): Also called genital damp itch. Itching of the genitals with redness, swelling, dampness, and exudation is mostly attributable to liver-gallbladder damp-heat pouring down through the channels.

Pudendal itch (外阴瘙痒 wài yīn sào yǎng): Itching of the female external genitals or vagina. It is attributed to liver-gallbladder damp-heat pouring downward or liver-kidney yīn vacuity.
