A pimple growing underneath, also known as a boil, is an acute bacterial purulent inflammation of the hair follicle and its surrounding tissues, mostly due to Staphylococcus aureus infection, but occasionally due to Staphylococcus epidermidis or other pathogens. General treatment, medication and surgery can be used to improve the condition.
1. General treatment: keep the skin underneath clean, avoid excessive sweating on the boils in summer or hot environment, take bath and change underwear frequently, pay attention to protect the skin and avoid epidermal injury.
2. Medication: If it is an early boil, 20% ichthyol ointment and mupirocin ointment can be used externally when it is not suppurated; for boils with large lesions, recurrent episodes and ineffective local treatment, antibacterial drugs such as amoxicillin and cephalosporin should be taken orally.
3. Surgery: If the following boils are serious, with multiple pus spots, purplish-brown surface or pus discharge, timely surgery is needed. The boil should be cut open and drained to remove the pus and the tissue that has not yet become pus but has been inactivated, and the pus cavity should be filled with saline and bandaged with dry gauze.
Boils should not be punctured with a needle or squeezed without authorization, so as not to aggravate the condition by triggering local skin infections; it is necessary to consult a doctor in a timely manner, and take targeted treatment under the guidance of the doctor.
