What should I do if the blister on my hand breaks and it hurts a lot?

Burst blisters on the hand can be very painful and may be caused by burns, scalds, injuries, allergies, or other reasons. Methods to manage a burst blister include cleaning, disinfecting, and dressing the wound. Detailed instructions are as follows:

1. Cleaning

After a blister bursts, an open wound forms on the skin surface, making it susceptible to bacterial and other contaminants. Therefore, cleaning is necessary. Proper cleaning removes dirt and bacteria around the wound, reduces the risk of infection, and promotes healing. It is recommended to gently wash the skin around the wound with warm water and soap, then pat dry with a clean towel. If the wound is severe, prompt medical attention is advised.

2. Disinfection

Disinfection helps kill bacteria and viruses around the wound, reducing infection risk and supporting healing. Use antiseptics such as alcohol or iodophor to disinfect the skin surrounding the wound, then gently pat dry with a clean towel.

3. Dressing

After a blister bursts, the wound is prone to contamination, so it should be dressed. Dressing protects the wound from bacteria and other pollutants, reduces pain and discomfort, and supports healing. First, disinfect the skin around the wound with an antiseptic, then cover it with sterile gauze or a bandage. Ensure the dressing is neither too tight nor too loose to avoid impairing blood circulation and wound healing.

In addition, under a doctor's guidance, anti-inflammatory and pain-relieving ointments such as erythromycin ointment or prickly heat cream may be applied for treatment. Avoid scratching the injured area with hands and keep it away from dirt to prevent infection.
