When the body appears insignificant small pain, most men will ignore, or play the instinct of endurance. However, the United States “Men’s Health” magazine recently pointed out that there are seven kinds of pain is a man can not ignore, because of the huge health risks buried in it. 1, sudden pain in the groin. Pain in the inner thighs also accompanied by swelling may be testicular torsion, that is, impaired blood circulation within the spermatic cord, causing testicular ischemia or even necrosis. Seeking medical attention within 4 to 6 hours of the onset of symptoms can effectively restore testicular function; however, if delayed after 12 to 24 hours, irreversible damage to the testicles can occur. This symptom may also be due to epididymal infection caused by improper underwear wear, and ultrasound should be performed to determine this. 2. Severe pain in the back. If something as trivial as bending over to clean can trigger extreme pain, and hot compresses, rest and painkillers do not help, and the injury is not caused by exercise, then it may be caused by an aneurysm or a kidney stone, and the pain in the latter will be more intense. It is best to receive a CT scan as soon as possible to determine the cause. 3. Persistent foot pain or anterior tibial pain (calf pain). If there is persistent pain in the back of the foot and lower leg that worsens with exercise and does not go away at rest, and pain medication does not help relieve the symptoms, then it may be a fatigue fracture caused by overtraining or exercise. It is best to have an X-ray scan to determine the location of the fracture, and to stop all strenuous activities until it heals. 4. Strong stabbing pain in the abdomen. This pain is like being cut by a knife and may be a result of inflammation of the abdominal organs, such as appendicitis, pancreatitis or cholecystitis. The specific judgment is: pain in the lower right side of the abdomen may be appendicitis; pain in the upper part of the abdomen with elevated white blood cell level may be cholecystitis; pain below the sternum may be pancreatitis. 5. Transient chest pain. This pain comes and goes quickly, jolts the pain and then disappears, may be caused by indigestion or heart attack, should go to the hospital as soon as possible to check whether the heart tissue is damaged. 6. Swelling and pain in the legs. One calf in particular is swollen and painful to the touch, with a burning sensation from the inside out. It may be due to blood clots caused by abnormal clotting of blood in the deep veins, which can cause life-threatening pulmonary tethering in serious cases if medical attention is not sought in time. It is best to do venography as soon as possible to determine the location and extent of the clot, and then use drugs to eliminate the clot. 7. Painful urination. Not only does it hurt when relieving oneself, but the rusty color of urine may be caused by cystitis or even bladder cancer. Smoking is the main cause of this disease. Once detected, the earlier the treatment, the higher the chance of cure.
