Blisters are small pockets of fluid that form in the upper layers of the skin, typically occurring when the outer layer of the skin is damaged. This fluid accumulates under the affected skin, providing cushioning to the tissue beneath. Both the fluid and the blister itself serve to protect the tissue from further damage and facilitate healing. Generally, it’s advisable to leave blisters undisturbed, as they safeguard the underlying skin. Popping blisters can heighten the risk of infection. In most cases, blisters heal naturally without requiring medical intervention. However, there are exceptions. Let’s explore how to treat different types of blisters:
Friction Blisters
It’s crucial to preserve the unbroken skin over a blister as it acts as a natural barrier against infection. Avoid piercing a blister with any sharp object, as this can lead to infection and hinder healing. Small blisters can be covered with a plaster, while larger ones should be covered with a gauze pad or dressing taped securely. For blisters likely to burst, such as those on the sole of the foot, use a soft dressing to cushion the area. Remember to change the dressing daily and wash your hands before touching the blister to prevent infection. Eventually, the fluid in the blister will be reabsorbed naturally, and the skin will return to its normal state.
Burst Blisters
After a blister has burst, it’s best to leave it alone. Avoid peeling off the dead skin atop the blister, and let the fluid drain naturally. Cover the blister and the surrounding area with a dry, sterile dressing. Hydrocolloid dressings, found in pharmacies, can be a good option. If the top layer of dead skin has been rubbed off, leave the remaining skin at the edges undisturbed. If the blister is on your foot, refrain from wearing shoes as they may have been the cause.
Blood Blisters
It’s crucial to avoid touching blood blisters and let them heal naturally. In case of rupture, maintain cleanliness and dryness in the affected area, and protect it with a sterile dressing to prevent infection. Applying an ice pack immediately after injury may alleviate pain. Remember, if a blister breaks, cleanse the area with soap and water, then apply a bandage. For large or painful blisters, seek medical attention; your doctor may drain them and apply an antibacterial cream to prevent infection.
