Cervical spondylosis is a condition that can cause chest discomfort. The main situations in which cervical spondylosis causes chest discomfort are as follows. First, in the process of cervical spondylosis, it may also be accompanied by degeneration of the thoracic spine. In this case, the patient will often experience pain in the thoracic back and there may be corresponding difficulty in breathing. Second, in the process of the onset of cervical spondylosis, there may be some radiating pain in the chest, especially in the anterior chest, due to the stimulation of some nerve roots, and then the patient may mistakenly think that the corresponding lesion has occurred here. Third, in the process of sympathetic cervical spondylosis, some cardiovascular lesions may be caused by the stimulation of sympathetic nerves. For example, it may cause the patient to feel panic, chest palpitations and other discomfort. Fourth, during the onset of cervical spondylosis, it may lead to the aggravation of some pre-existing chest lesions of the patient. For example, the severe pain caused by cervical spondylosis may aggravate the patient’s pre-existing coronary heart disease, hypertension, or respiratory diseases, and the patient may feel discomfort in the chest at this time.
