Mechanical injuries to the testicles as a result of a fall, sports and transport accidents or a blow (often a kick) in the groin are in the top ranking of the most terrifyingly painful experiences that a man can experience. Loss of balance, watery eyes, sharp headache, breaking out in a cold sweat, a sharp drop in blood pressure, collapse, muscle spasms, vomiting and fainting are common manifestations after mechanical trauma to the scrotum – the skin pouch in which the testicles are located. In the case of particularly severe trauma, most of these symptoms appear almost simultaneously, which can also lead to a life-threatening shock state. Inevitably after a strong enough blow, the man’s body goes into a near shock state from the pain. Nerve signals traveling from the affected area to the brain travel at speeds of over 400 km/h and lead to the release of a neurotransmitter from the testicles known as Substance P. It signals the need for pain relief, the strength of which can even lead to cardiac arrest. fit. When these signals reach the brain, it triggers several processes almost simultaneously. The first is the release of endorphins – natural pain-relieving compounds that suppress some of the pain sensations and relieve the signal overload of the nervous system as a result of severe stress. Unfortunately, the large amount of endorphins needed to suppress severe pain causes blood oxygen levels to drop, resulting in a long-lasting throbbing headache and near-constant nausea. A brain component known as the pelvic sympathetic ganglion is also often activated, causing the eyes to water. The severe pain has an overstimulating effect on the inner ear as well, leading to changes in the fluid present in it – the main reason for the loss of balance and vomiting. Because the pain receptors of the testicles are connected to those of the abdominal cavity, the pain of the blow quickly spreads to the lower abdomen – the reason why most victims are holding their stomachs, bent over or on the ground in a fetal position. Abdominal pain is also a factor leading to vomiting after a stroke. Experts advise taking some immediate steps after sustaining a blow to the groin. NEWS_MORE_BOX Even if the victim manages to stay on his feet, he must lie on his back. This leads to a faster normalization of adequate blood circulation to the brain, which relieves headaches and lowers the activity of the sympathetic ganglia. The lying position also relieves the strain on the inguinal ligaments, which reduces pain. Tearing, sweating, vomiting and a sudden rise in body temperature (due to intense stress) can lead to rapid dehydration. The victim should move to a cool room and take at least 0.3-0.5 liters of water to compensate for the shock effect of dehydration. It is desirable to put ice on the affected area, but for no more than 2-3 minutes,it can be repeated after 10-15 min – this way the potential inflammation of the tissues is optimally alleviated. Prompt administration of pain relievers, especially those with anti-inflammatory properties, such as acetaminophen, is also advised. If the intense pain lasts more than an hour and sweating, fever, nausea and vomiting are still present, or swelling of the testicles or changes in the color of the scrotum are noted, emergency medical attention is required. Trauma can cause testicular torsion (twisting of the testicle), internal bleeding (in the scrotum and testicles), and tissue tears that directly threaten not only a man’s fertility, but his life.
