"How long does it take for a separated fingernail from the nail bed to heal after injury?"

After a fingernail injury leading to separation of the nail from the flesh, it usually takes about a month for healing. However, if an infection occurs later, the recovery time will depend on the specific duration of the infection's resolution. Detailed analysis is as follows:

1. Separation Due to Trauma

If the nail separates from the flesh due to trauma, congestion often occurs, causing the nail to detach from the flesh beneath. Prompt medical attention is required. If necessary, the nail may need to be removed to clear the congested blood, which aids in wound recovery. Simultaneously, iodine tincture or alcohol can be used for anti-inflammatory treatment. Topical medications such as Mupirocin Ointment or Erythromycin Ointment can be applied to the affected area. Avoid exposing the wound to water, and expect wound healing in approximately one month, during which time attention to hygiene is crucial to prevent infection.

2. Separation Due to Fungal Infection

If a fingernail injury is accompanied by fungal infection, it can also lead to separation of the nail from the flesh. In such cases, antifungal treatment is typically necessary. Topical antifungal medications like Ketoconazole or Bifonazole can be selected for treatment, with an estimated recovery time of 1 to 3 months. After the nail separates from the flesh due to trauma, it is also important to supplement nail nutrition by promptly consuming vitamins A, calcium, iron, and other nutrients. When using medications, patients should follow the advice of a doctor to avoid adverse effects from unauthorized medication use.
