Does someone who had a spontaneous pneumothorax ALWAYS have reoccurences? My 20 year old daughter had a small one (under 10% according to her Dr.) which has resolved itself since her first xray 2 days ago.  Will she continue to have them?  She is normal weight, height and has no history of problems other than Juvenile Myoclonic Epilepsy (she hasnt' had a "jerk" in 7 years and takes Keppra).

Summarized question: Is spontaneous pneumothorax a recurring disease?
