The exact time it takes for a boil to go away on its own depends on the individual’s body type and the severity of the condition, and cannot be generalized. Severe boils that do not go away on their own need to be seen by a hospital dermatologist or surgeon. Boils are a common infectious skin disease, mainly manifesting as purulent inflammation of deep hair follicles and surrounding tissues, and are commonly found on the head, face, neck and buttocks. It is a follicular inflammatory papule at the beginning, and a small hard nodule with redness, swelling and pain is visible on the local skin, which becomes soft and wavering in the center after a few days, and a yellowish-white dotted pus plug appears on the top. After the pus plug is dislodged, pus, blood and necrotic tissue are removed, and then the inflammation gradually subsides and heals. The time for complete regression is related to individual’s physical condition and severity, and it is about two weeks for less infected people, and recurrent or prolonged for more infected or immunocompromised people. Once a boil is found, it is recommended to seek medical attention and active treatment to avoid local pus breakage, crusting and shedding, which can cause more obvious tissue defects and form pits or scarring. If accompanied by systemic symptoms such as fever or improper care of the ruptured area, it may be prolonged. During treatment, care should be taken to keep the skin clean and dry, and avoid squeezing and scratching by oneself.
