Blistering

A blister is basically a patch of raised skin that is filled with fluid called serum. This serum is excreted by tissues and blood vessels that go through trauma, such as intense force or friction. The liquid then collects between the gap of the epidermis and dermis. When the area heals, the serum is reabsorbed back into the body. The blister then crusts over and the scab peels off after a few days. Blisters are usually itchy, painful. The area around them may feel warm and swollen. Whatever the cause is of your blisters, you will definitely experience discomfort to some extent.

Blisters are commonly found on the hands and the feet, but they may also manifest on the other parts of your body, depending on the cause. Some of the causes of blisters include friction, chemical irritation, medical conditions like herpes and chickenpox, and side effects of medications.
