What reason is the ache before shoulder?

Factor 2: coronary heart disease. Coronary heart disease is a heart disease caused by coronary artery stenosis or spasm. During the attack, the myocardium will accumulate modern metabolites due to ischemia and hypoxia. The metabolites stimulate the afferent terminals of the cardiac autonomic nerve (they are actually pain receptors). The receptors transmit the pain signals to the brain through the sympathetic ganglia and the corresponding spinal nerves in front of 1-5 thoracic vertebrae, producing pain sensation in the brain. Because the pain in the shoulder, sternum and left little finger is also transmitted to the brain through the sympathetic ganglia and corresponding spinal nerves in front of the L-5 thoracic vertebrae, the brain sometimes can't tell whether the pain comes from the heart, sternum and shoulder. Sometimes, people with coronary heart disease in peacetime is often the symptoms of shoulder pain, this kind of pain will sometimes cover the pain of other parts, so shoulder pain should be highly vigilant. General coronary heart disease patients in addition to shoulder pain, there will be sternal or precordial compression like discomfort.

Cervical spondylosis caused by back pain, neck movement is often caused by nerve root compression stimulation, there will be electric shock like feeling, for reflex, accompanied by numbness of fingers, limb cold and abnormal skin sensation of compressed nerve innervation area, but no shoulder joint movement disorder.

Factor 3: apical lung cancer. There are many nerve plexuses around the apex of the lung, such as the cervical plexus that innervates the skin and muscles of the neck, and the brachial plexus that innervates the skin and muscles of the shoulder, back and upper limbs. When cancer occurs in the apex of the lung, the developing cancer tissue can compress or invade these nerves, such as brachial plexus, and shoulder pain can occur. This kind of pain is usually in the armpit, to the upper limb medial radiation burning pain, especially at night. If the shoulder is severely compressed, it will also affect the movement of the shoulder and upper limbs.
