Had a spontaneous lung collapse, what happens now?

Size: Smaller collapse often heals. Larger may need drainage/chest tube. 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.

Depends: Usually responds to, treatment, including chest tube. Some have recurrence and need video assisted bleb stapling and mechanical pleural, scarring- called pleurodiesis. Some individuals may have opposite side issues. No smoking regular follow-up.
