Chest pain like a tendon pulling can be seen in muscle strain, intercostal neuralgia, chest cavity inflammation and infection. 1. Muscle strain: excessive pulling during exercise or labor causes muscle fiber rupture and other injuries, and pain occurs along the direction of the muscle fiber. When the chest muscle is strained, there may be a tendon pulling pain in the chest, accompanied by hard lumps and swelling formed by muscle tension. 2. Intercostal neuralgia: the pain is distributed along the intercostal space and mostly occurs unilaterally, so when intercostal neuralgia occurs, the feeling of a tendon tugging at the chest may also occur. 3. Inflammatory infections in the chest cavity: such as pleurisy, pneumonia, etc., resulting in pleural adhesions or adhesion bands between the lungs and the chest wall, resulting in the sensation of a tugging pain in the chest like a tendon. There are many other reasons for chest pain like a tendon pulling, if the pain can not be relieved, you should go to the hospital for further examination and treatment.
