1, stabbing belly button Why stabbing the belly button in the mud and dirt will cause stomach pain? This is because most of this dirt is the natural metabolic secretions of the skin, including the shedding of epithelial cells, human secretion of sebum, in addition to some external dust, plus the navel is the thinnest part of the abdominal wall, there is no subcutaneous fat under it, directly connected to the fascia, peritoneum, force picking, scraping the navel, will cause irritation to the internal organs of the abdominal cavity, easily cause discomfort in the digestive system, and even stomach pain. If you break the skin covering the wall of the navel, it is easy to cause umbilitis secondary to bacterial infection, and once it deteriorates, it may become septic and aggravate the condition. The correct way to clean up the navel should be to take a bath with water to moisten it naturally, and then scrub it with a soft cotton gauze, the mud and dirt inside will fall off naturally. 2, pick your nose In addition to the navel, there are nasal eyes, ear eyes can not just go with hard objects or hand stabbing. The two most common diseases in our dermatology department are caused by dermatitis and HPV infection in the face and nasal cavity leading to wart. If you accidentally pierce the blood vessels in the nasal cavity, it may cause more than nosebleeds. 3. Ear pulling There are also many people who pull out their ears because of itching in the external ear canal or simply to enjoy the thrill of pulling out their ears. However, because the ear canal is particularly deep, digging the tools deep into the ear canal is particularly likely to cause damage to the ear canal, and a slight impropriety can touch the eardrum. Once the eardrum is pierced and perforated, a person’s hearing will be greatly reduced. In addition, if a bacterial infection develops secondary to this, it can also cause a bacterial infection leading to Daniosis or an HPV infection leading to a wart (common wart, pictured below). So it is recommended that if the ear canal is really itchy, it is best to use soft cotton swabs and not to use sharp things like fingernails or iron skewers to pull out the ear. So love to poke these holes friends to pay attention to, must change their bad habits, do not pick the navel, do not pull out the nostrils or ears Oh.
