The term “Small Intestine Meridian” is generally used in folklore, but in Traditional Chinese Medicine (TCM), it refers to abnormal changes in the Small Intestine Meridian of the Sun of the Hand, which may result in yellowing of the eyes, deafness, sore throat, lesser abdominal pain, swelling of the cheeks, pain in the posterior edge of the outer shoulder and arm and pain in the meridian’s pathways. Pain may appear in the body surface circulation sites of the Small Intestine meridian, which starts at the ulnar end of the little finger, goes up the ulnar side of the hand to the wrist, and travels up the posterior edge of the lateral side of the arm. After reaching the shoulder joint, it winds around the scapular region and then passes from the great vertebrae point down into the notochord. One of the branch veins, after separating from the defective basin, travels up the neck to the cheeks, up to the lateral canthus of the eye, and then backward into the ear. Another branch chakra, partially exiting from the cheeks, travels upward from below the eye socket, up against the side of the nose, and terminates in the inner canthus of the eye. The meridians are the channels through which qi and blood flow. If the meridians are not accessible and the qi and blood do not run smoothly, pain and diseases related to the areas crossed by the meridians may occur. Since the Small Intestine meridian passes through the inner and outer canthus of the eye, the ear, the throat, and the cheeks, abnormal changes in the meridian can lead to yellowing of the eyes, sore throat, deafness, and swelling of the cheeks, etc. If these symptoms occur, it is recommended to go to a doctor promptly. If the above symptoms occur, it is recommended to go to the regular hospital in time for active treatment, do not blindly use drugs or acupuncture.
