Squeezing pus boils is generally not recommended, and squeezing a pus boil may cause the infection to spread. Boils are a common skin condition, usually a subacute purulent infection caused by Staphylococcus aureus invading the hair follicle. It usually occurs on the face, neck and buttocks, and is associated with poor hygiene habits or eczema, etc. A pus-filled boil may be a sign of improvement, but there is also a certain chance that it will lead to the spread of the inflammation, so squeezing and picking at it with your hands won’t necessarily make it better. First of all, try to avoid picking and squeezing after the pus breaks out because it is difficult to clean up the pus if it is not handled well, and it is easy to recur and secondary infections may occur, which may spread the inflammation; secondly, carbuncles may appear after the merger of several boils, which may worsen the infections, which is very detrimental to the recovery of the patient; and squeezing of the triangular area of the face is strictly prohibited, which may cause meningitis and other serious consequences. After pus breaks out, boils need to be actively sterilized and treated. After being sterilized with iodine povidone, antibiotic medications such as mupirocin ointment can be used under the guidance of a doctor for anti-infection treatment. Patients should pay attention to skin cleanliness and a light diet, and seek immediate medical attention if discomfort occurs.
