It is possible to get a nail infection in the fingernail. If the tissue around the fingernail breaks down, outside bacteria may enter the tissue and lead to nail fungus. After the clinical development of nail fungus, the nail and surrounding tissues will become red and swollen, and the patient will feel pain and localized tenderness. If the inflammation progresses further, an abscess may form, and the pain and redness may expand, and fluctuations may be palpable on palpation. After the diagnosis of nail infection, it is important to provide anti-inflammatory treatment in a timely manner, either with oral antibiotics or with topical ointments with anti-inflammatory effects. If an abscess is formed, in addition to anti-inflammatory treatment, surgical treatment is also required, which generally means that the abscess is incised and drained, and the wound cannot be sutured and needs to be changed regularly until it heals.
