I'm sorry to hear about your burn and the pus coming from the sore, which suggests an infection. For such wounds, a topical antibiotic and antiseptic ointment can help prevent the infection from spreading and promote healing.

One commonly used ointment is Metrogyl-P 2% Ointment, which contains povidone-iodine and metronidazole. This combination works against a broad range of bacteria and helps in early wound healing. It is applied externally on the affected area.

Important points to consider:

• Clean the wound gently with clean water before applying the ointment.
• Avoid contact of the ointment with your eyes.
• If you notice increased redness, swelling, or worsening pain, or if you have any allergies or thyroid issues, consult a doctor promptly.
• Since this ointment requires a prescription, please see a dermatologist or a general physician to get an appropriate evaluation and prescription.

If the infection worsens or you develop fever, seek medical attention immediately.

In summary:

• Clean the burn gently.
• Apply an antibiotic-antiseptic ointment like Metrogyl-P 2% after consulting a doctor.
• Monitor for signs of worsening infection.
• Consult a dermatologist or physician for proper care and prescription.
