Blister
A medical Blister is a small pocket of fluid that forms on the upper layer of the skin. It is usually caused by friction, burning, freezing, chemical exposure, or infection. Blisters can be filled with a clear fluid, serum, blood, or pus. The most common type of medical Blister is a friction Blister, which is caused by excess rubbing or pressure on the skin. This is often seen in athletes or other people who wear tight shoes or engage in activities that cause excessive friction on their skin. Blisters can also form from burns, chemical exposure, or an infection. Blisters can be painful and can cause discomfort. They can also lead to skin infections if not treated properly. Medical Blisters should be treated with an antibacterial ointment or cream and then covered with a bandage to keep them clean and protected. Once the Blister has healed, the skin should be kept moisturized to prevent future Blisters.
