Each sign has internal, external and structural rulerships. Internally, Pisces rules the lymphatic system, synovial fluids and functions of the glands in general. Externally, it rules the feet and toes and structurally the bones of the feet.

Swelling, allergic reaction to drugs, injuries to the feet and related problems are common complaints, but the Piscean emotional nature can also make them vulnerable to psychosomatic illness. The susceptibility of the Piscean nature to drugs and alcohol as a way of dealing with the pressures of the world needs to be addressed in a sensitive and realistic way.
