Why does the left rib hurt when inhaling suddenly, and the deeper the breath, the more painful it gets?

When inhaling suddenly, there is pain in the left rib, and the deeper the breath, the more intense the pain. This may be caused by conditions such as left-sided pneumothorax or left intercostal neuralgia. It is recommended to undergo treatment after identifying the cause.

1. Left Pneumothorax: This refers to the accumulation of air in the left pleural cavity, which may be caused by factors such as trauma or tumors. Patients may experience cough, chest tightness, swelling pain, and severe dyspnea. Therefore, sudden inhalation may cause pain in the left rib, and the deeper the breath, the greater the pain. Patients can usually undergo surgical treatment.

2. Left Intercostal Neuralgia: This refers to pain in one or more intercostal nerve innervation areas caused by various reasons, manifesting as paroxysmal or persistent pain. Therefore, sudden inhalation may cause pain under the left rib, and the deeper the breath, the greater the pain. Patients can generally take medications such as oral carbamazepine tablets or pregabalin capsules.

Patients are advised to visit the hospital for examination to identify the cause and undergo corresponding treatment. They should not take medication without authorization and should rest adequately, avoiding strenuous exercise.
