The bones under the right breast are the ribs and the cartilage of the rib cage, and if there is a slight pain, the first thing you should think of is whether the local area has suffered a definite trauma, no matter whether it is strained or sprained, and the pain can be relieved after resting. If the pain is not more than a week, you can first apply topical medicines to activate blood circulation and remove blood stasis, or topical pain relieving medicines with western medicine ingredients. If the pain disappears quickly, you can continue to apply drugs and reduce activities. If the pain does not disappear, you should go to the regular hospital for local radiography, or ask a specialist for examination, and then carry out symptomatic treatment after the initial diagnosis. Most of the pain in this position is directly related to acute or chronic injuries, and once the chest is overactive, it will make the local pain significantly worse.
