Blisters are small pockets of fluid that usually form in the upper layers of skin after it's been damaged. Blisters can develop anywhere on the body but are most common on the hands and feet.
Hidden Bow Pin Black Pleaser by Tie Satin Platform Pump Couture Up Cutiepie Heel Polka Dot With Fluid collects under the damaged skin, cushioning the tissue underneath. This protects the tissue from further damage and allows it to heal.
Most blisters are filled with a clear fluid (serum), but may be filled with blood (blood blisters) or pus if they become inflamed or infected.
Most blisters heal naturally after three to seven days and don't require medical attention.
It's important to avoid bursting the blister, because this could lead to an infection or slow down the healing process.
If the blister does burst, don't peel off the dead skin. Instead, allow the fluid inside the blister to drain and cover the area with a dry, sterile dressing to protect it from infection until it heals.

When to see your GP
See your GP if you have blisters that:
- you think are infected
- are very painful
- keep coming back
An infected blister will be filled with yellow or green pus and may be painful, red and hot.
It's important not to ignore an infected blister because it could lead to secondary impetigo (a contagious bacterial infection of the skin) and further complications, such as cellulitis or sepsis.Women’s 359 Orient Pepe Capsicum Trainers Pink Frida Jeans 1UqF07Ff5
