During pregnancy, the mother's constitution is deficient and susceptible to wind pathogens, which damage the meridians and collaterals of the Taiyang (Greater Yang) channel. Subsequently, if exposed to a combination of wind and cold pathogens, an attack manifests as trismus (lockjaw) and stiffness of the back. This condition is termed "Jing" (Spasm). Its clinical presentation includes chest oppression and discomfort.
