Energy in stomach meridian that shouldn't be there

The nature of “wind” conditions are that they move. So one of the ways for distinguishing different “types” of arthritis (“bi syndromes”) for example would be what we call “fixed” bi is predominately from dampness - “my left knee always hurts” and “wandering” bi is related to wind - “some days my shoulder hurts and other times its my left hip”.

As with most things in Chinese Medicine (and in nature from which it’s observations come) it can get more layered. So, yes, many psychological issues are involved with the concept of “wind” in Chinese Medicine - but it is rare that that it all they are involved with. “Wind” can arise, and often does, from damp-heat for example - so the stagnation and frustration in movement so to speak from an internal system generates a force and this force rises upward. A somewhat straightforward example of this would be stroke from dietary factors - so a person has a long history of poor diet, generating dampness in the spleen and liver systems (i.e. things such as cholesterol and general inflammatory markers) and then this creates a “wind-strike” - i.e. the damage to the blood vessel.

The general “trick” with Chinese Medicine is to not think too linearly as we are trained in the west - but to think relationally and relatively. So something is not always yang - but it is yang in relation the related yin aspects - damp in relation to relative levels of dryness, etc.
