Paronychia has occurred, mainly due to infection of the nail groove or surrounding tissues. Minor puncture wounds, bruises, or injuries from cutting nails too deeply can all cause paronychia.

When paronychia occurs, it is essential to control it promptly during the acute phase by using broad-spectrum antibiotics for treatment. This can include oral administration of amoxicillin, cefaclor sustained-release tablets, cefdinir dispersible tablets, etc. Topically, ichthyol ointment or mupirocin ointment can be applied for treatment.

If symptoms do not improve, the most thorough treatment method is to promptly visit a formal hospital's surgical department for nail removal treatment.

With paronychia, it is essential to avoid spicy and irritating foods in your diet, and do not attempt to squeeze the pus yourself, as it can easily lead to a worsening of the infection.
