Numbness in a finger after a burn suggests a severe injury, likely affecting below the dermis and damaging nerves, leading to abnormal sensations and numbness.

After a finger is burned, it should be immediately rinsed with cold or running water for at least thirty minutes to cool the burn down. Then, proceed to a hospital for proper care, such as disinfection, wrapping with gauze for protection, and possibly applying burn ointment to promote recovery. Follow the doctor's instructions for daily dressing changes, and take antibiotics as prescribed to prevent and treat infections.

How to deal with a skin scald that has broken the skin?

After a skin burn breaks the skin, if the area is relatively small and there is no obvious swelling, a moisturizing burn ointment can be applied. If the area is larger and accompanied by some exudation and swelling, it is necessary to go to the hospital for timely treatment. Under the guidance of a doctor, antibiotic ointment should be applied, and oral antibiotics should be taken. Common choices include Cefalexin, Cefradine dispersible tablets, and erythromycin for anti-infection treatment. Antibiotics can be used if there is no allergic reaction to them. If severe burn symptoms occur, combined with serious infections, swelling, and significant exudation, it is crucial to go to the hospital for medical treatment immediately. Severe cases may require hospitalization. Do not scratch the skin yourself, and avoid spicy and irritating food.

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

How long it takes for a finger burn to improve depends on the severity of the burn, and one cannot generalize. If the burn affects only the epidermal layer, recovery or complete healing generally takes about a week. This is because skin metabolism, which takes about 5 to 7 days to renew, especially at burned areas such as on the face or fingers, can take longer to heal. Moreover, if the burn is deeper, reaching below the dermal layer, the recovery time depends on how deep the burn is. It might take 2 weeks or even up to a month for complete recovery. Therefore, the duration needed for a burn to heal depends on the severity of the burn.

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.

Why do burns on fingers blister?

After a finger is scalded, the high local temperature causes some damage underneath the skin, resulting in the skin oozing fluid. This fluid accumulates and forms blisters, so after a scald, the finger may develop a blister or several blisters. Once a blister has formed, try not to puncture it. It can be disinfected with iodine and allowed to absorb slowly on its own. Puncturing the blister might lead to infection, worsening the condition. Generally, after a finger is scalded and a blister forms, it suffices to disinfect the area. Of course, it is crucial to cool the finger quickly after the scald to minimize further damage.

What should I do if my finger swells up from a burn?

After a finger burn, it should immediately be rinsed with cold or running water continuously for at least half an hour to cool down the damaged skin. Then, use iodine or alcohol to disinfect the area, followed by covering it with a dressing. If swelling occurs, cold packs with ice water can be applied. Alternatively, magnesium sulfate wet compresses or more traditional remedies, such as continually applying potato slices, can help reduce the swelling. However, these methods will require some time to take effect. The main goal is to alleviate symptoms through anti-inflammatory and pain relief treatments, allowing the inflammation of the soft tissues to subside gradually and the swelling to reduce.
