After being scalded by oil and experiencing itchy sensations, there are several scenarios:

First, after the acute phase of an oil burn, if there is no local infection, the patient may feel itching in the burned area. This sensation is caused by the proliferation and repair of new epidermal tissue, which is a normal occurrence. The patient should not worry, but it is important to remember not to scratch the area to prevent local infection and rupture of the skin tissue, which could delay the healing of the wound;

The second scenario occurs when there is an infection in the burn. The patient will also feel itching in the affected area, and they should go to the hospital promptly for local debridement and disinfection;

The third scenario occurs when the wound heals but leaves a scar, which can also cause itching. In this case, scar treatment medications can be applied for treatment.

How to treat burns from cupping therapy

For minor cupping burns without blistering, apply local iodine for disinfection and keep the area dry. If there are small blisters, let the skin absorb them naturally, disinfect daily with iodine, and keep the blistered skin intact. If the blisters are larger, clean a needle to puncture them and release the fluid, then keep the area dry and disinfect daily with iodine. If the patient has diabetes, or if the burn is severe or covers a large area, seek treatment at a burn clinic.

Why does a burn on the finger hurt so much?

After a finger is scalded, it can be extremely painful. This is related to the sensitivity of the nerve endings in the fingers. The limbs and fingers have a dense distribution of nerves, and when scalded or injured, the pain can be very pronounced, resulting in sharp and stabbing symptoms. After a finger is scalded, it is important to cool it down promptly to reduce the damage to the skin tissue. Depending on the condition, relevant medications should be used to prevent infection. Medications can also be used to reduce the symptoms of pain. If the pain is particularly severe, appropriate pain relief medication can be used (please use medications under the guidance of a doctor).

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 should I do about the dead skin from a burn on my finger?

Generally, after a finger is scalded, damage occurs to the skin's soft tissues, and some of the skin may necrotize. Once necrosis sets in, the blood supply to the affected area becomes poor. At this point, it is necessary for the body to promptly remove this dead skin. It is best to have debridement under the guidance of a physician to remove the necrotic skin and soft tissue; otherwise, these necrotic tissues can easily become infected, which in turn can cause harm to the body. Therefore, after necrosis occurs following a finger scald, it is advisable to immediately visit the emergency department of a hospital for debridement. Removing the necrotic tissue and performing proper dressing and disinfection will promote the rapid recovery and healing of the skin tissues.

How to deal with blisters from a burn when there is no burn ointment available

After a burn causes blisters, it indicates that the burn is quite severe. If you don’t have burn ointment, there are two other methods that can be adopted. The first method is applicable if the blister is small and contains little fluid. You can protect the blister from infection by thoroughly disinfecting the area and then covering it with sterile gauze to wait for the blister to be absorbed. If the blister is large and filled with significant fluid, you can use a needle to drain it or make a small incision at its lowest point to let the fluid out. Then, thoroughly disinfect the area and cover it with a sterile gauze pad. You can wait for the fluid to be absorbed as much as possible while preventing infection. Avoid contacting the burn with water to protect the area and prevent secondary infection.
