“The sequence of bodily symptoms usually starts at the left foot or toes, either as a mild tingling stimulus or as cramps. The stimulus continues up the left leg to the hip. In extreme cases, there is a paralysis of the foot and of the whole leg. Loss of sensation in large areas of the skin of the leg may occur. From the hip the stimulus moves up the spine to the head. Here sometimes severe headaches (pressurelike) may develop. In case of prolonged and severe pressures in the head, degeneration of the optical nerve may set in, with accompanying visual impairment. Loss of memory and general disorientation may occur.”
