The burning, numb, tingling feet of diabetic peripheral neuropathy are read through the long-standing internal heat of a Yin-deficiency pattern that, over time, congeals into Blood stasis in the vessels of the extremities. Offered as education alongside medical care.
Synthetic Teaching Case This is a representative educational case, synthesized from recurring clinical patterns. It does not describe a specific patient, and no identifying information from any real patient is used. It illustrates diagnostic reasoning only — it is not medical advice, not a claim of treatment outcome, and individual situations vary. Always consult a licensed healthcare provider.
Consider a composite presentation seen repeatedly in clinic: an older adult under medical care for diabetes who develops burning, numbness, tingling, or a “pins and needles” quality in both feet, often worse at night, sometimes with dryness and a sense of heat in the soles. The symmetry and the distal (feet-first) distribution are characteristic.
Beyond the chief complaint, a cluster of accompanying signs recurs in this pattern:
Neuropathy is diagnosed and managed medically. The classical framework reads the burning-and-numb, dry, night-worse quality through the combination of an underlying Yin-deficiency heat with a downstream stasis of Blood in the small vessels of the feet.
The wasting-thirst (Xiao-Ke) background of diabetes is classically a Yin deficiency with internal heat (see case 017). Over time, that internal heat and the impaired movement of Blood allow stasis to form in the vessels of the extremities. Where Blood no longer reaches and nourishes the nerves of the feet, numbness results; where stasis and heat irritate, burning and tingling result.
On the four axes this reads as Interior, with a Deficient Yin base generating Heat, plus a local Excess of Blood stasis distally. It combines the deficiency root of the diabetes pattern (017) with the stasis mechanism seen in the Achilles case (015), now expressed in the nerves of the feet.
Burning-numb feet are read as an internal-heat deficiency that has let Blood congeal in the extremities — so the direction is to nourish Yin and move the stasis, alongside medical care.
The differential is against a purely deficiency-cold numbness (pale, cold, relieved by warmth, without burning) and against a purely Qi-deficiency numbness (see case 045). The Yin-deficiency-with-stasis reading is made specifically for the burning, dry, night-worse, symmetrical distal picture on a diabetic background.
Diabetic neuropathy is a serious complication of a medically managed disease, with real risks to the feet. This case is strictly educational and supportive: it does not treat neuropathy or diabetes, does not replace medical care, glucose management, or foot care, and is not a reason to alter any of these. It describes acupuncture considered alongside comprehensive medical care.
For this Yin-deficiency-with-stasis reading, the supportive direction is to nourish Yin, clear internal heat, and invigorate Blood to move the stasis in the extremities, as supportive care alongside medical management. This describes a direction of supportive care, not a guaranteed outcome; responses vary by individual, and medical care should continue as directed.
The diagnostic logic in this case applies the CALee framework — constitutional individuation, relational process, and the non-fixed self — developed in the following publications:
The book develops the Yin-deficiency and Blood-stasis patterns and their combination in the extremities.
The Deficiency/Excess and Cold/Heat axes used to read the combined pattern in Step 2.
