Recently, a young man, who had mumps two months ago and had bilateral orchitis, took medicine to reduce the fever, swelling and pain, but his testicles became soft and small with vague pain. In recent years, the number of cases like this is gradually increasing, especially in spring, the season when everything grows. The patient is suffering from a disease called “mumps and testicles”, which is an acute infectious disease caused by wind and temperature. The reason for this is that the external wind and warmth of the evil poison, from the mouth and nose into the congestion of the Shaoyang meridian depressed and not dispersed, knotted in the cheeks, the foot Shaoyang vein from the outer canthus of the eyes up to the corner of the head, the lower ear, around the ear and travel, the evil into the Shaoyang, the meridian congestion, qi and blood flow is blocked, so the cheeks under the ear diffuse swelling and pain; Shaoyang and Turk’s Yin are each other, the disease is transmitted to each other, the foot Turk’s Yin vein along the less abdominal complex yin organ, if the heavier the evil, can be complicated by the less abdominal pain, The testicles are swollen and painful, that is, “lead testicle”. The mumps and testicles is the western mumps and testicular inflammation, mostly in the winter and spring, caused by viral infection, the virus is a paramyxovirus, transmitted by saliva droplets through the respiratory tract, mostly in adolescence, testicular inflammation often occurs 4-6 days after the appearance of mumps, but also without mumps symptoms, about 70% unilateral, 50% of the affected testes atrophy, because the parotid gland is similar to the basement membrane of the testes and secondary The testicular autoimmune reaction is caused by the parotid gland and the testis, mostly in patients with physical deviations or untimely treatment, and bilateral testicular involvement can eventually lead to testicular atrophy or even loss of fertility. Therefore, it is important to pay attention to the early diagnosis and treatment of mumps, especially for adolescent male patients who should be treated with active intervention to reduce or stop the appearance of sequelae (meningitis, pancreatitis, orchitis, etc.). Once scrotal pain occurs after mumps, it should be given high priority and promptly seen at a regular hospital specialist.
