Answer:
Do not puncture a blister unless it is large, painful, or likely to be further irritated. The fluid-filled blister keeps the underlying skin clean, which prevents infection and promotes healing.Let the fluid drain, but leave the overlying skin in place. Apply an ointment such as petroleum jelly to the blister and cover it with a nonstick gauze bandage. If a rash appears, stop using the ointment. Follow-up care.
