Vatnsbólgu

Vatnsbólgu is an Icelandic term that translates to "water swelling" or "water blister." It refers to a small, fluid-filled sac that can form on the skin. These blisters are typically benign and can arise from various causes. Common triggers include friction, such as from ill-fitting shoes or repetitive hand movements, leading to a separation of skin layers where fluid accumulates. Burns, particularly superficial ones, can also result in vatnsbólgu. Exposure to certain irritants or allergens might also cause these fluid-filled lesions to develop.

The appearance of vatnsbólgu is usually a clear or slightly cloudy blister, ranging in size from a pinprick to a few millimeters in diameter. They are generally painless unless they become infected or are located in an area subject to constant pressure or stretching. Treatment typically involves keeping the area clean and dry to prevent infection. If the blister is intact, it is often best to leave it undisturbed as the fluid provides a natural protective barrier for the underlying skin. If the blister breaks, the exposed skin should be gently cleaned and covered with a sterile bandage. Medical attention may be necessary if signs of infection, such as redness, warmth, increased pain, or pus, become apparent. Vatnsbólgu usually resolves on its own without complications.
