Do You Have Phlegm Stagnation Muscle Spasms in Your Back? Stabbing Back Pain Might Be Myofascial Pain Syndrome

The phlegm stagnation muscle spasm described in the Donguibogam is explained in modern medicine in a way very similar to myofascial pain syndrome. Myofascial pain syndrome is a condition where tender points, known as trigger points, form in the fascia enveloping the muscles, causing pain. These trigger points can be felt as small taut nodules. When pressed, they cause sharp tenderness and trigger referred pain that radiates to surrounding areas. The muscles in our body are composed of delicate bundles of muscle fibers. Due to persistent stress, poor posture, repetitive tasks, overuse, or sudden trauma, parts of the muscle fibers can become microscopically damaged or excessively contracted. These taut muscle fibers hinder local blood circulation, leading to an insufficient supply of oxygen and nutrients. As fatigue substances such as lactic acid accumulate within the tissue, an inflammatory response is triggered. This inflammatory reaction forms a trigger point and irritates nearby nerves, creating a vicious cycle that continuously sends pain signals to the brain. The back and shoulder areas are especially prone to constant tension from prolonged smartphone use and computer work. When a posture with the head lowered or shoulders hunched continues for an extended time, specific muscles are overused or abnormally shortened, impeding blood supply and ultimately activating trigger points. Going beyond localized tightness, trigger points sometimes accompany autonomic nervous system symptoms such as headaches, arm numbness, and dizziness. This occurs because the trigger points stimulate the nervous system, affecting adjacent areas or the autonomic nervous system. Although it begins as mild muscle pain, leaving it unattended can lead to a chronic condition that markedly lowers quality of life, making early and active care important.
