It was thought to be a disease of excessive sweating, but the small
bumps of clear liquid under formerly clear
skin do
not form in the same areas as sweat glands. Instead, a huge amount of bubbles of clear liquid appear underneath the skin of fingers, palms of the hand, and soles of feet. They are sometimes itchy and painful. The liquid eventually drains from the blisters back into the body, and the skin flakes off leaving a tender area of clear skin painful to touch.
