What is the best treatment option for a single furuncle with no surrounding cellulitis?

The best treatment for a single furuncle, especially when there is no surrounding cellulitis, is incision and drainage. This method is effective because furuncles, commonly known as boils, are localized collections of pus that form due to infection of hair follicles. Incising and draining the pus not only provides immediate relief from pressure and pain but also promotes healing by allowing the body to expel the infectious material.

In cases where a furuncle is present without accompanying cellulitis, aggressive interventions such as systemic antibiotics are not typically warranted, as the primary issue is localized and can often be resolved by drainage. Additionally, simply watching the furuncle without intervention may lead to increased discomfort and prolong the healing process, as the body may not effectively resolve the infection on its own. Cold compression may provide some symptomatic relief but does not address the underlying infection or the need for drainage, making it inadequate as a standalone treatment.

Therefore, incision and drainage serve as the most direct and effective approach for managing a solitary furuncle in the absence of surrounding cellulitis, ensuring a quicker recovery and reduced risk of complications.
