How to take care of blister?

To care for a blister, first, keep it clean and protected. If the blister is small and intact, avoid popping it to prevent infection; cover it with a sterile bandage. If it bursts, gently clean the area with soap and water, apply an antibiotic ointment, and cover it with a bandage. Monitor for signs of infection, such as increased redness or pus, and consult a healthcare professional if needed.
