After accidentally burning a finger, even if the skin isn't broken, it should be treated quickly to prevent further absorption of heat and further damage to the skin, soft tissue, and muscles. Many skin and soft tissue burns can appear after a period of time. The burned finger should be immediately rinsed with ice water or cold water, for about 20-30 minutes. If there are ice cubes available at home, they can be used to locally apply ice. This can quickly and effectively reduce the heat damage to the skin and soft tissues, improve the prognosis, shorten the course of treatment, and at the same time, attention should be paid to prevent infection.

How many days will it take for a burn on the finger to heal?

The relief from a finger burn can take days, depending on the severity of the burn and the extent of damage to the skin, soft tissues, and muscles. For mild burns, only the epidermal layer is damaged, and in general, such cases will gradually heal within about a week. On the other hand, if the burn affects the skin, soft tissues, and muscles, recovery can take a very long time, especially if complications such as infections occur, which will extend the treatment period. After burning a finger, do not blindly treat it at home; instead, seek analysis and a subsequent treatment plan from a professional doctor.

Can you drink alcohol after a burn?

After a burn, it is not advisable to drink alcohol. This is because the burn site is in the repair phase of healing and has not fully recovered. During this period, more nutrients and a relatively normal metabolic state are required. Alcohol or alcoholic beverages contain ethanol, which can cause dilation of blood vessels and skin, as well as an increase in heart contraction. It can also lead to an increase in skin exudation, thereby worsening the condition of the burn wound, or causing infection at the wound, leading to inflammatory symptoms. The patient may experience itchiness at the burn site. Therefore, it is not advisable to drink alcohol after a burn to avoid delaying the healing process at the burnt area.

Do you need to bandage after a burn?

Whether bandaging is needed depends on the severity of the burn. Generally, if it's just simple redness, no bandaging is needed. After the local skin is scalded, if blisters form, it is considered a superficial second-degree burn. You can first rinse with cold water or soak in cold water for more than half an hour, or apply ice to reduce the pain. Before bandaging, clean the wound with hydrogen peroxide, then disinfect the wound surface with iodine, release the water inside the blister while keeping the blister skin, then apply burn ointment on the gauze, cover the wound surface, and then use multiple layers of dry gauze for bandaging. Generally, change the dressing every three days, and recovery can occur within two weeks, leaving no scars later. Patients should maintain a light diet, eat fresh vegetables and fruits, avoid spicy and stimulating food, and abstain from alcohol.

What to do if the pain persists after a burn?

After a burn, the pain persists primarily because the wound was not properly treated. The most common and simplest method in the early stages of a burn is to soak the burn in cold water or rinse it under running water for over half an hour. This can help wash away the residual heat on the surface, especially making it more effective for acid or alkali burns. Alternatively, you can use an ice pack to cool the area. After cooling, apply some burn ointment. If the pain is severe, pain-relieving medication can be used to treat symptoms, such as ibuprofen. If the pain is unbearable, it is advised that the patient should go to the hospital for timely examination and symptomatic treatment.

Can the blisters from a burn be punctured?

Whether to rupture the blisters that appear after a burn depends on the situation. If the blisters caused by the burn are relatively small, it is not necessary to puncture them, as this is better for the skin and can provide protection. However, if the blisters that appear after the burn are large, it is advisable to rupture them, because if the blisters are too large, the fluid cannot be completely absorbed by the body, which can hinder healing.
