There are four main possibilities for right chest pain: first, neurosis, including intercostal neuralgia and chondromalacia, the clinical symptoms are mainly hidden chest pain, and the pain is more aggravated after exertion or cold. Secondly, pleurisy, mostly secondary to lung infection, manifests as limited hidden pain in the chest, and the pain is aggravated by deep breathing or violent coughing. Third, cystic hyperplasia of the breast, a common benign disease of the breast, is clinically manifested by palpable hyperplastic nodules in the breast, accompanied by vague pain and discomfort in the breast, and the pain is mostly aggravated before menstruation and can be significantly relieved after menstruation. Fourthly, lung cancer, commonly found in elderly men, mostly with a long-term smoking history, manifests as vague pain in the chest, which may be accompanied by cough or hemoptysis. Therefore, if the right chest is sometimes painful, you should consult a doctor in time to clarify the nature of the lesion and avoid using drugs blindly, so as not to lose more than you gain.
