How long does it take to heal from a lung puncture from a fall?

Days to seal: Months to heal. Lung punctures from trauma can cause your long to collapse (pneumothorax), a chest tube will help get rid of the air and normalize the pressure (days) as the puncture seals. After the tube is removed, the lung will heal, but it will take months to heal completely, so you should pressure extremes (skydiving, scuba diving, etc).

Patience: Chest tube drainage/evacuation will often resolve pressure imbalance instantly. The hole in the lung from trauma or spontaneous collapse can potentially seal in just a few days (like a scab). The lung tissue takes longer to fully heal, depending on type of injury. If from trauma, associated chest wall injury (rib fractures, etc...) as well as chest tube site may take weeks to months to heal.
