Under normal circumstances the pain and discomfort caused by breast disease is not significantly related to inhalation, if the pain around the breast occurs during inhalation should be noted to consider chest lesions. There are two common conditions: first, pleurisy, mainly due to the spread of lung infection to the pleura, causing acute and chronic infectious lesions of the pleura, manifested as stabbing pain or dull pain in the chest, and aggravated by deep breathing or violent coughing. Secondly, neurosis, the main cause of which is related to autonomic nerve dysfunction, the pain is mostly distributed along the rib cage and is distended or stabbing pain and aggravated by exertion or inspiration. All in all, inspiration does not cause breast pain, if it is clear that breast pain should go to the regular hospital breast surgery or general surgery to perform breast ultrasound examination, clear breast lesions and reasonable treatment under the guidance of a specialist.
