Water and Fluid retention in legs, also known as edema, is a medical condition caused by abnormal accumulation of water or fluids in the bodyâs tissues. Though excess water can be accumulated anywhere in the body, the most common areas are the ankles and legs.
The usual cause of water blisters on the legs is constant friction or the frequent brushing of your skin against fabric or new shoes. Water blisters can be painful when the blisters burst. Water blisters are usually located on the heels and are caused by a new pair of shoes especially leather and other shoes made of hard materials. Cigarette burns and other burns on the skin can also cause water blisters.
