| Painful Diabetic Neuropathy (PDN) is a common and intractable chronic complication of diabetes. Clinically, it is characterized mainly by symmetric pain, numbness, and paresthesia in the distal extremities, severely affecting patients" quality of life. While modern medicine offers certain efficacy in controlling blood glucose and providing symptomatic analgesia, it has limitations such as numerous side effects, a tendency for drug resistance, and an inability to reverse nerve damage. Based on years of clinical practice,Director Wu Fangtingproposes that the core pathogenesis of PDN lies in"weakness of the spleen and stomach, deficiency of qi and blood, and obstruction of the collaterals by phlegm and stasis."The treatment emphasizes the fundamental principles of tonifying qi and strengthening the spleen, resolving phlegm and dispelling stasis, and unblocking the collaterals to relieve pain.This article systematically summarizes Director Wu"s academic insights and clinical experience in diagnosing and treating PDN, aiming to provide a reference for the traditional Chinese medicine management of this condition. |
