Whether a fingertip cut exposing flesh can heal on its own is usually related to the degree of damage at the site of the cut, and there is a possibility of self-healing, but serious cases still need to be treated in a hospital. If the fingertip wound is small, not much bleeding, and the skin near the wound is relatively clean, and the finger can be freely bent, the condition is mild. Because the skin tissue has good proliferation and repair ability, so the patient after simple disinfection, dressing treatment, if the wound is well together, can be self-healing, do not need to worry too much. If the cut has a large area of exposed flesh and a large amount of bleeding, it will not heal on its own, so the patient should go to the emergency department of the hospital in a timely manner, perform other symptomatic treatments such as suturing, and follow medical advice to receive tetanus vaccination and sterile treatment to avoid infection. Patients with fingertip cuts should avoid cold, spicy and irritating foods and hair products, and do not get their fingers wet for the time being to avoid secondary infection, which may cause the wound to persist.
