How long does it take for the blister to heal from ant bite?

Ant bites: Bites from ants, especially fire ants, can last 1-2 weeks. Do not scratch them or they can get infected. Use cortisone or benedryl cream for the itch. See a doctor if there is sign on infection.

Protective Cushion: With injury to our skin, inflammation occurs which means the area becomes red, warm, tender and with swelling. Swelling occurs under the skin layers and causes them to bulge creating a protective fluid cushion called a blister. As the area heals, the fluid will be resorbed or when no longer needed, the blister opens and it drains. This should take about a week. Keep it covered and protected.
