Has the friction blister popped and what steps should be taken for proper care and healing?

If a friction blister has popped, it is important to clean the area with mild soap and water, apply an antibiotic ointment, and cover it with a bandage to prevent infection. Keep the area clean and dry, and avoid further friction or pressure on the blister to promote healing. If there are signs of infection, such as increased pain, redness, or pus, seek medical attention.
