Fire boils should not be squeezed to drain the pus. Fire boils are boils, and squeezing is contraindicated in fire boils; squeezing can cause the germs to spread. The pus plug can be picked out with a needle tip after sterilization. Boils are the common name for boils, which are acute suppurative infections of hair follicles and their surrounding tissues, mostly caused by Staphylococcus aureus. Early on, boils are characterized by localized redness, swelling, heat, pain and hardness of the skin, which can be relieved by applying hot compresses or ichthyol ointment. After the red and swollen stage, yellowish-white pus spots will appear on the top of the boil with fluctuating sensation, i.e. pus plugs in the suppurative stage. At this time, the local skin can be sterilized with iodine povidone, and then the tip of a knife or a needle can be used to pick up the skin and remove the pus plugs. However, it is forbidden to squeeze the pus, as squeezing will easily lead to the spread of germs along the veins or lymphatic channels. Especially in the dangerous triangle formed from the root of the nose to the corners of the mouth on both sides of the face, it is forbidden to squeeze and drain the pus, and the germs are easy to retrograde infection along the venous system, which can lead to cavernous sinus thrombophlebitis in the skull in serious cases. Patients are advised not to squeeze the boil to drain the pus, but to pick out the pus plug to drain the pus. Meanwhile, if fever, headache, and general discomfort occurs, it should be promptly consulted.
