Blisters are fluid-filled sacs that form on the skin and can be caused by various factors, with the most common being:

• Continuous rubbing or friction on the skin can lead to blisters, such as from ill-fitting shoes or repetitive motion.
• Exposure to excessive heat, like sunburn or contact with hot objects, can cause heat blisters.
• Thermal burns, chemical burns, or even sunburn can result in blister formation.
• Certain infections, like herpes or impetigo, can produce blisters as symptoms.
• Allergic reactions

Symptoms of blisters include:

• Appear as raised bumps filled with clear or pus-like fluid
• Tender or painful
• Redness and swelling
• Inflammation and itchiness

How To Identify the Signs of an Infected Blister

Even though blisters will generally heal on their own, the affected area may be infected if not properly attended to. As a result, you must be able to watch for sure signs before the situation escalates.

Identifying signs of an infected blister is crucial to prevent complications. Look out for these indicators of infection:

• It could be infected if the blister becomes more painful instead of improving over time.
• The area around the blister may become increasingly red and warm to the touch.
• An infected blister can cause swelling, extending beyond the initial blistered area.
• Yellow or green discharge from the blister is a vital sign of infection.
• A fever could indicate a systemic infection, especially if accompanied by other signs.
• If the blister shows no signs of healing or worsens after a few days, it may be infected.

At-Home Treatment For a Blister

Treating an infected blister and knowing when to seek medical attention is essential for preventing complications. Here's what you can do and when to involve a healthcare professional:

1. Wash your hands: Always start by thoroughly washing your hands to prevent introducing more bacteria.
2. Clean the area: Clean the infected blister and the surrounding skin with mild soap and warm water. Avoid scrubbing or causing further damage.
3. Apply an antibiotic ointment: After cleaning, apply an over-the-counter antibiotic ointment to help prevent infection.
4. Cover the blister: Use a sterile, non-stick bandage or dressing to cover the blister. Change it daily or if it becomes wet or dirty.
5. Keep it dry: Keep the blister and dressing dry to prevent further infection. 

When to Seek Medical Attention For a Blister

If the infection worsens despite home care or spreads to other areas, seek immediate medical attention.
