The common causes of radiating pain in the elbow include cervical radiculopathy, elbow arthritis and angina pectoris. 1. Nerve root cervical spondylosis: including cervical disc protrusion, osteophytes, degenerative changes, etc. When the protruding discs or osteophytes compress the cervical nerve roots, the nerves are stimulated by pulling and affecting the normal conduction, resulting in radiating pain in the arm. In addition to the radiating pain in the arm, the disease is also accompanied by obvious neck pain, numbness of the skin on the affected side, and weakening of muscle strength. 2. Elbow arthritis: such as lateral epicondylitis of the humerus and medial epicondylitis of the humerus, in the case of elbow joint strain, the muscles form aseptic inflammation in the bone attachment point, resulting in radiating pain in the elbow joint, and sometimes radiating to the forearm. 3. Angina pectoris: it is a clinical syndrome triggered by insufficient blood supply to coronary arteries and acute temporary ischemia and hypoxia of myocardium, with episodes of chest pain or chest discomfort as the main manifestation. Chest pain can affect most of the precordial area, and the pain can be radiated to the left shoulder and the inner side of the front of the left upper limb, and up to the ring finger and pinky finger. There may be other causes of radiating pain in the elbow, and patients should consult a doctor in time to make a clear diagnosis and then carry out targeted treatment.
