What indicates Stomach Cold Invasion?

Stomach Cold Invasion is characterized by a sudden onset of symptoms, one of which is the sudden pain in the epigastrium. This type of pain is often sharp and can be triggered by exposure to cold or by consuming cold foods or drinks. In Traditional Chinese Medicine (TCM), the presence of cold in the stomach can create an obstruction, leading to intense discomfort.

This symptom aligns well with the condition being described, as it highlights the acute nature of the pain associated with a stomach cold. The suddenness points to a more immediate invasion of cold, impacting the stomach's outer layers.

Other factors such as a thick yellow coat on a red tongue typically indicate heat in the stomach rather than cold. Hiccups and nausea can arise from various conditions but are not specific to cold invasion in this context. Dull epigastric pain is more indicative of a deficiency or chronic issue rather than the acute symptomology associated with a cold invasion of the stomach. Thus, the indicator of sudden pain in the epigastrium is a key feature of Stomach Cold Invasion.
