Among diseases presenting with chest pain, intercostal neuralgia is characterized by sharp, paroxysmal pain that follows the distribution of the intercostal nerves. It typically involves tenderness in the anterior cutaneous branch of the intercostal nerve, located at the sternum and along the inner edge of the rectus abdominis muscle. This condition presents as a band-like pain on one side of the chest, often accompanied by sensory abnormalities such as numbness and tingling in the same area. It is more common in women, especially affecting the left 5th to 9th intercostal nerves. Deep breathing, coughing, and other movements of the rib cage can trigger pain episodes, so it is essential to differentiate this condition from diseases affecting the muscles, fascia, and pleura.In traditional Korean medicine, treatment involves IntraMuscular Electro Acupuncture Stimulation Treatment (IMEAST), which helps relieve pressure on the affected nerves by targeting the muscles around them and quickly eliminating any metabolic waste within the muscles.Treatment Case 1: 35-Year-Old White FemaleThe patient experienced pain in her right side while breathing, starting three days prior.
