Blisters

What Are Blisters?

• Fluid-filled bubbles on the outer layer of skin
• Filled with clear fluid (serous fluid), but sometimes blood or pus if infected
• Act as a protective cushion to allow healing underneath

🔍 Common Causes:

• Friction or rubbing (from tight shoes or repetitive motion)
• Burns (thermal, chemical, or sunburn)
• Frostbite
• Allergic reactions
• Infections (like chickenpox or herpes)

⚠️ Symptoms:

• Raised, fluid-filled bump on the skin
• Redness or irritation around the blister
• Pain or tenderness
• Sometimes itching or burning before blister appears

🏠 Treatment:

Do:

• Leave the blister intact to protect underlying skin
• Keep it clean and dry
• Cover with a sterile bandage or blister pad
• If the blister is large or painful, drain it carefully with a sterilized needle (do not remove the skin flap)
• Apply antibiotic ointment if opened

Don’t:

• Pop or peel the blister skin unnecessarily (risk of infection)
• Pick at the blister or expose it to dirt

🛡️ Prevention Tips:

• Wear properly fitting shoes and socks
• Use moisture-wicking socks
• Apply lubricants or powders to reduce friction
• Break in new shoes gradually
• Use protective pads or tape on hotspots

When to See a Doctor:

• Signs of infection (increased redness, warmth, pus, red streaks)
• Large, painful blisters
• Blisters caused by burns or chemical exposure
• Blisters in people with diabetes or poor circulation
