I got pneumothorax

From 2 days ago, I've felt pain of left chest. When I woke up in this morning, the pain got wrose. I couldn't endure, so I went to the hospital. 

After taking x-ray my chest, the doctor said you got pneumothorax. Slim, 10-30years men liable to get. In my case, the condition was light, so maybe I can't be serious.

But if I get worse, I must have an operation. I hope that I get better.
