For acute paronychia, broad-spectrum antibiotics are mainly used for topical application. Options include mupirocin ointment, fusidic acid cream, or erythromycin ointment for symptomatic treatment. At the same time, it is important to wear loose shoes to avoid squeezing the foot and worsening the symptoms. If there is no improvement in symptoms after three days of using topical medications, surgical treatment may be considered based on the specific situation. For chronic paronychia, antibacterial or antifungal medications may be used. Medication should be gradually discontinued after the inflammation has subsided. During treatment, keep the affected area dry and avoid contact with water. Paronychia refers to an infection of the tissue surrounding the nail, typically presenting with localized swelling and pain.
