Blood blister problem ?!

A blister is a defense mechanism of our body!. It is an area of the skin wherein the outer layer (epidermis) separates from the next layer (dermis)!. A clear liquid called serum collects within this gap while the epidermis re-grows from beneath!. Serum is the component of blood that remains after clotting agents and red blood cells have been removed!. It seeps out from the surrounding tissues as a reaction to trauma!. The serum serves as a cushion that protects the tissue underneath, guarding it against further damage until it heals!. Other bodily fluids may also form within the bubble, such as pus if it becomes infected!. Blood may also form within if the blister is a result of sub-dermal bleeding!. This is when a tiny blood vessel near the surface of the skin ruptures and blood seeps into a tear between the skin
