Hiertymät

Hiertymät, commonly known as blisters, are small pockets of fluid that form on the skin. They are typically caused by friction, such as from ill-fitting shoes or repetitive movements. Burns, both thermal and chemical, can also lead to hiertymät. Certain medical conditions, including infections and autoimmune diseases, can manifest as blisters as well.

The fluid within a hiertymä is usually clear serum, a part of the blood that leaks out when the skin is damaged. If the blister is caused by a severe burn or infection, the fluid may appear cloudy or even bloody. The skin's natural response to injury is to create a protective cushion of fluid to prevent further damage to the underlying tissue and to aid in the healing process.

Most minor hiertymät heal on their own without intervention. It is generally advised not to pop them, as this can increase the risk of infection. If a hiertymä is large, painful, or shows signs of infection (redness, swelling, pus), it may require medical attention. In such cases, a healthcare professional might drain the blister safely or prescribe treatment for any underlying cause. Prevention is key, and this often involves wearing appropriate footwear, using protective gear during activities that cause friction, and being mindful of potential burn hazards.
