Fire boils, known in medical terminology as boils, are acute purulent inflammation of hair follicles and perifollicular tissues. Fire boils usually appear as follicular inflammatory papules or nodules that are cone-shaped, bright red, soy-sized or larger, with a reddish base and localized with fever, swelling and pain as well as pressure pain, and may also be accompanied by systemic symptoms such as fever.1. Typical symptoms: Initial onset of localized red, swollen, hot and painful nodules that gradually swell and bulge in a conical shape. As the disease progresses, the central tissue of the nodule becomes soft, pus embolism appears, and the symptoms continue to worsen and expand in scope. Later, as the pus is discharged, the inflammatory reaction disappears until it is cured. 2. Accompanying symptoms: Usually patients can have no systemic reactions, but if the patient has poor resistance and the onset of the disease is in a blood flow-rich area, systemic reactions such as fever, headache and chills may occur. In addition, special attention should be paid to boils near the “danger triangle”, i.e., around the nose and upper lip, where boils should not be picked or pressed at will, as they can easily cause inflammatory material to be pushed into the intracranial cavernous sinuses, resulting in purulent cavernous sinusitis, which can lead to high fever, headache, and even coma, which can be life-threatening. If the patient has more serious infection symptoms, should promptly consult a doctor, follow the doctor’s instructions to carry out anti-infection treatment, may need to cefoxitin sodium or penicillin sodium treatment, local may be with fusidic acid ointment coating, specific medication should be combined with their own situation under the guidance of the doctor.
