In the clinic, the reason why the patient has the phenomenon of deep inhalation pain in the right side of the ribs may be that the patient’s right side of the ribs suffers from costochondritis, localized costal neuritis, fasciitis, bursitis and other diseases. When the patient inhales deeply, the right intercostal muscle will produce contraction movement, which can stimulate the local lesions and make the patient have pain phenomenon. In addition, the patient’s right rib cage, due to long-term chronic exertion, strain or acute trauma, can injure the intercostal muscles between the right ribs, producing lactic acid metabolism disorders in the intercostal muscles. When the patient inhales deeply, it can also pull the local damaged muscle tissue, which will also cause the patient to produce pain manifestation, and can be treated with hot compresses or reduce the amount of activity, so that this pain phenomenon can be relieved.
