A popped blister occurs when the fluid-filled pocket under the skin’s outer layer breaks open. These blisters typically develop from friction or injury, acting as a protective cushion. When the skin barrier is compromised, it becomes susceptible to contaminants. Proper attention is important to prevent infection and promote healing.
Immediate Steps for a Popped Blister
First, thoroughly wash your hands with mild soap and warm water to prevent bacteria. Then, gently cleanse the blister area with mild soap and water. This cleaning removes any debris or contaminants.
Leave the loose skin flap in place. This skin acts as a natural barrier, protecting the delicate skin beneath and shielding it from bacteria. Removing this flap increases infection risk and can delay healing. After cleaning, gently pat the area dry with a clean cloth or allow it to air dry completely.
Protecting the Area
After cleaning and drying, apply a thin layer of antibiotic ointment or petroleum jelly. This helps maintain a moist environment, conducive to healing, and reduces bacterial infection risk. The ointment provides a protective barrier.
Next, cover the area with a sterile, non-stick bandage or gauze pad. Hydrocolloid dressings are an option, offering cushioning, pain relief, and a moist healing environment for faster recovery. These dressings can remain in place for several days. Secure the dressing firmly, ensuring it covers the affected area without irritation. For foot blisters, a doughnut-shaped moleskin pad can relieve direct pressure.
Change the dressing daily, or more frequently if it becomes wet, dirty, or dislodged. Each time, gently cleanse the area with mild soap and water, and reapply the ointment. This maintains a clean healing environment and allows for regular inspection.
Recognizing Complications
Most popped blisters heal without issues, but recognize signs of infection. Watch for increasing redness, swelling, warmth, or pus (yellow or green, with foul odor). Red streaks spreading from the blister are a serious sign.
Persistent or worsening pain indicates possible infection. Fever or chills signal the infection may be spreading. If any of these signs appear, if the blister is unusually large or painful, or if it doesn’t improve within a week, consult a healthcare provider. This can help prevent more serious complications.
