Lying with body curled can be the consequence of several so-called “patterns of disharmony” in Chinese Medicine.
Chinese Medicine sees the body as a system, not a sum of isolated parts. A "pattern" is when the system's harmony is disrupted, leading to symptoms or signs that something is wrong (like lying with body curled here). It is similar to the concept of disease in Western Medicine but not quite: a Western disease can often be explained by several Chinese patterns and vice-versa.
A pattern often manifests itself in a combination of symptoms that, at first glance, do not seem necessarily related to each others. For instance here lying with body curled is often associated with feeling of cold, diarrhea and chills in the pattern “Lesser Yin Cold Transformation”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of lying with body curled we’ve identified that a herbal formula called Si Ni Tang can help treat the patterns behind the symptom.
In Chinese Medicine lying with body curled is a symptom for the pattern "Lesser Yin Cold Transformation". Below is a small explanation for it with links for more details.
