If you have a pneumothorax, there is usually adhesion between the lungs and the chest wall, which may be the cause of your pain.

Adhesion may tear after strenuous exercise, leading to pneumothorax or hemopneumothorax.

If the discomfort is aggravated, it is recommended to go to the hospital for X-ray examination. If you want a radical cure, you can choose: thoracoscope+pleural swab.

If you don't want to receive treatment, you can choose to reduce your activities to avoid the above things.
