Spigelia. [Sep]
This remedy holds about the same relation to the left side of the head that Sanguinaria does to the right side. The pains are neuralgic in character, settle over the left eye,and they are apt to follow the course of the sun, beginning in the morning, reaching the acme at noon and subsiding at sunset. There is often a sensation as if the head were open along the vertex. Noises and jarring of the bed, as under Belladonna, aggravate the pain; stooping and change of weather also make the pain worse. The pure neuralgic character of the pain, and its left side preference, should lead to the remedy.
