Inflamed toenails that have pus need to be removed promptly and treated with oral or even intravenous antibiotics. If the nail is not removed, the pus cavity will not be fully drained and will not be cured, so the toenail must be removed. In addition, pus is a serious infection and needs to be treated with antibiotics. For patients without underlying diseases and with good immunity, oral antibiotics can be given, while for patients with malnutrition or combined with underlying diseases, intravenous antibiotics are needed to achieve a good anti-infection effect.
