Blisters are small pockets of fluid that form within the upper layers of the skin. They can contain clear fluid, blood, or pus, depending on whether the blister is infected. Blisters often form due to friction or rubbing of the skin, exposure to extreme temperatures like frostbite or sunburn, chemical exposure, or certain medical conditions such as chickenpox or eczema. To treat a blister, the area should be cleaned and disinfected before carefully draining the fluid with a sterile needle. Then, apply antibiotic ointment and change the bandage regularly.
