Carbuncle is contagious and may spread to other parts of the body. It may spread to other people too.Several skin boils come together to form carbuncle. The lump formed is filled with pus, fluid and dead tissue. The fluid inside the carbuncle may drain out, however in some cases the mass may be so deep that the fluid cannot drain on its own.
