In Chinese medicine, [Wind] in the body can manifest as jerky movement, dizziness, uncoordination or symptoms that migrate from one region of the body to another. [Wind] invading the surface of the body manifests as soreness, itching and sensitivity of the skin and muscles. Disorders of external [Wind] are the common cold and flu, characterized by dizziness and migratory pains in the joints, muscles and head. Diseases of internal [Wind] are characterized by labile emotions, vertigo, tremors, headaches, seizures, strokes and the agitation of the [Liver Qi] by fever, [Deficiency] of [Blood] or emotional instability.
The nature of [Wind] is movement that rises and falls unpredictably. [Wind] is deemed the most virulent of all the climatic forces that can engender disharmony. It creates an intense draught, the nature of which is to unsettle and disrupt surface and interior conditions. [Wind] can steal into the body, like wind through cracks, and create a portal through which the other adverse climates -- [Dampness], [Dryness], [Cold] and [Heat] -- can enter the body.
