Blisters



Yesterday, we walked going to the train station from the long weekend.
We hiked just for twenty minutes with my sandals on.

In the train station, I felt so weak and so tired. I could not just walk straight because of the excruciating pain.
To my surprised, I got 7 blisters on my left foot and 4 blisters on my right foot. It was just very painful. This is my first time having a lot of blisters.

Now, I’ve learned the lesson to put on trainers shoes every time we come and visit places, relatives and friends.

Blister is a collection of fluid underneath the top layer of skin (epidermis). One that is more than 5 mm in diameter with thin walls and is full of watery fluid is called a bulla or a bleb. There are many causes of blisters including burns, vesicant agents, friction forces, and diseases of the skin.

A blister or bulla is a defense mechanism of the human body. When the outer (epidermis) layer of the skin separates from the fiber layer (dermis), a pool of lymph and other bodily fluids collect between these layers while the skin re-grows from underneath.
