How does modern medicine explain a pricking pain in the center of the back? Surprisingly, it shares many commonalities with the wisdom of Donguibogam. First, the observation in Donguibogam that prolonged sitting damages the kidney aligns closely with the sedentary lifestyle of modern individuals. Sitting in a slouched posture for long hours increases the load on the spine, readily misaligning the thoracic vertebrae and lumbar vertebra. This causes muscles surrounding the back—such as the rhomboid muscle, trapezius muscle, and erector spinae—to become excessively tense or weakened, leading to muscular imbalance. In this process, sensitive trigger points form within the muscles, causing pricking or tingling pain. This condition is also known as myofascial pain syndrome.
Furthermore, the classical phrase 'wind, cold, dampness, and heat damage qi and blood' can be understood in modern medicine as inflammation and a circulatory disorder. When inflammation occurs, algogens are secreted to stimulate nerves, and inadequate blood circulation fails to supply sufficient oxygen and nutrients to muscles, worsening pain as waste products accumulate. In particular, when inflammation or dysfunction arises in the small joints connecting the spine to the ribs—such as the costovertebral joint or facet joint—it can cause sharp, stabbing pain in the center of the back. In severe cases, this pain can radiate toward the flank or anterior chest.
Additionally, the role of the kidney in Korean medicine can be linked to modern medicine's nervous system and endocrine system, particularly the function of the adrenal gland involved in the stress response. Chronic stress or overwork can disrupt the hypothalamic-pituitary-adrenal axis, which regulates the body's stress response. This causes an imbalance in cortisol, leading to decreased immunity, systemic fatigue, and chronic skeletal pain. When the body enters a state of chronic fatigue, it becomes more sensitive to pain from even minor stimuli. Although rare, visceral issues such as pancreatitis, cholecystitis, or heart disease can also manifest as back pain, making a professional evaluation essential if the pain persists or is accompanied by other symptoms.
In conclusion, a pricking pain in the center of the back is likely caused by a complex interplay of diverse factors rather than a simple muscle knot. It is a signal encompassing muscular issues, spinal joint dysfunction, nerve compression, inflammation, and systemic factors like stress. This is why we must listen carefully even to minor signals sent by our bodies.
