Hiya Irishlad. I have had two spontaneous pneumothrax,one in 1996 and one in 2004.After the second one I had surgery to try and prevent it happening again.The operation was called a pleurectomy and bullectomy. I have found this site very helpful in the past

All the members of the site have had pneumothorax.
How long did it take for your lung to reinflate?What percentage of your lung collapsed? Did you need a chest drain? These are all questions that will have a bearing on your long term recovery and risk of reccurrence.
