Paronychia generally should not be self-treated. The occurrence of paronychia is usually related to improper nail trimming or improper removal of hangnails; some are caused by bacterial infections, while others are due to fungal infections. It is advised not to self-treat paronychia, especially if there is an abscess, as it requires proper medical treatment at a hospital. Improper handling can easily lead to worsening of the infection, and pus drainage treatment should be conducted under the guidance of a doctor. If swelling and pain are significant, oral antibiotics might be necessary. In cases where there is no allergy to antibiotics, oral medications such as cefaclor sustained-release tablets or cefdinir dispersible tablets may be used. Attention should also be paid to the cleanliness of the affected area to avoid squeezing it oneself.
