"My Feet Burn Every Night"...Diabetic Neuropathic Pain: The Real Culprit Is Elsewhere

"Every night, it feels like my feet are on fire, and like thousands of needles are pricking them, making it impossible to sleep. Even the slightest brush of a blanket makes me jump."

The 68-year-old, who has suffered from diabetes for over 15 years, said he dreads the arrival of night. The pain and numbness in his feet, which were dormant during the day, invariably resurrected like monsters as darkness fell, consuming him. The neuropathic medications (such as gabapentin) prescribed by his doctor had long since lost their efficacy, leaving only dizziness. Recently, his glycated hemoglobin (HbA1c) had risen to 8.5%. He was slowly giving up on everything.

Why do diabetic patients suffer from such agonizing neuropathic pain? The explanation that nerves are simply 'damaged' due to high blood sugar is insufficient. To understand the root of the problem, we need to shift our perspective.

1. Your Nerves Are Starving


Let's imagine our body's nerves as 'tree roots' and our body as 'soil.' A body that has sustained high blood sugar for a long time is like 'desert soil,' parched and cracked by drought. As the soil dries out, the deepest roots (peripheral nerves in the toes and fingertips) begin to wither, deprived of nutrients.

The excruciating pain of diabetic neuropathy is precisely the desperate cry of these 'starving nerves.' Beyond mere nerve damage, it's the final scream as they slowly die, deprived even of the minimal nutrients (oxygen and blood) necessary for survival.

In Traditional Korean Medicine (TKM), this systemic state of nutrient deficiency and functional decline is termed **'Qi and Blood Deficiency (氣血兩虛).'** This signifies that both the body's energy (Qi) and its material foundation (Blood) are depleted, an insight that perfectly aligns with the 'parched soil' analogy.

2. Pain Blockage vs. Nutrient Supply: A Fundamentally Different Approach


Conventional neuropathic medications primarily focus on suppressing nerve channels that transmit pain signals. This is akin to gagging the nerve's 'mouth' because its screams are too loud. While it can reduce pain in the short term, it fails to address the underlying cause of 'starvation.' It's like propping up a withered tree with supports while the soil continues to dry out.

CASE STUDY: A Shift in Treatment Perspective

Traditional Korean Medicine (TKM) treatment, however, looks elsewhere. It aims to irrigate and fertilize the 'parched soil,' allowing the tree roots to regain the strength to thrive on their own. In other words, it focuses on promoting peripheral circulation to deliver nutrients to every corner of the nerve cells.

This is more than just suppressing symptoms; it's a fundamental treatment method that creates an 'environment' where nerves can recover on their own.

3. How to Bring Life-Giving Rain to Parched Soil


So, how exactly can we fertilize the 'soil'? The key is to replenish Qi and Blood (氣血) and clear blocked blood vessels.

Step 1: Restore Basic Vitality with Qi and Blood (氣血) Replenishment

  • The top priority is to replenish the body's foundation, depleted by prolonged illness. Herbal medicines such as Hwanggi (Astragalus), Insam (Ginseng), Danggui (Angelica gigas), and Sukjihwang (Rehmannia glutinosa preparata) are used to aid digestive function and promote blood production. This is like the first step of pouring water onto dry land.

Step 2: Nourish Nerves by Promoting Peripheral Circulation

  • Once Qi and Blood are sufficiently replenished, herbal medicines such as Gyeji (Cinnamon twig), Dansam (Salvia miltiorrhiza), and Useul (Achyranthes bidentata) are utilized to open pathways for blood to reach the fingertips and toes smoothly. This is the process of creating waterways to the very tips of the tree roots.

Step 3: Remove Blood Stasis (瘀血) and Manage Pain

  • Chronic circulatory dysfunction leads to the formation of 'Blood Stasis (瘀血),' a sticky blood waste product. When this is removed with herbal medicines such as Doin (Peach kernel) and Honghwa (Safflower), pain significantly decreases, and sensation begins to recover.

Most importantly, blood sugar management is crucial. No matter how good the nutrition supplied, if the 'poison' of high blood sugar continues to contaminate the soil, the tree will inevitably wither again. Only by correcting lifestyle habits under the guidance of a specialist, while simultaneously striving to fertilize the 'soil' of your body, can you finally find hope of breaking free from the agonizing cycle of pain.

I have met many patients who came after visiting multiple medical institutions and departments for persistent or recurrent conditions. Symptoms normally handled by different specialties—such as abdominal pain, headaches, palpitations, dizziness, and insomnia—may overlap in one person. Sometimes there is no clear improvement despite taking medication for each symptom, and being unwell gradually becomes part of daily life. In these cases, I look beyond individual diagnoses and examine how the symptoms connect and change together. Asking only about the most uncomfortable symptom today does not reveal the full course. I look at when the body first began to change and what happened after illness, surgery, childbirth, or starting and stopping medication. I also review changes in weight, diet, and sleep, then trace which symptoms improved with previous treatment and which remained. Test results, diagnoses, and the course of previous treatment are important for understanding the current condition. Clinical research in modern Korean medicine, physiological and pathological research in modern medicine, and observations recorded in classical Korean medicine texts offer different perspectives on the same body. Rather than fitting a patient into one perspective, I consider what each can and cannot explain and look for clues that connect symptoms and treatment histories that were previously considered separately.
