Hello,I suffered a  pneumothorax two weeks ago, they had to insert a chest tube to remove the air and reexpand the lung and after spending a week in the hospital I was released,I was cleared for work a week ago and it seemed like everyday I felt better and stronger.But tonight my chest area felt so sore, like I had been working out, and my shoulder area started aching,after a few hours I slowly started feeling better but my chest and back are still bothering me.I am not sure whether to go to the hospital now or just rest and see how I feel in the morning?

Summarized question: What is the treatment for pneumothorax?
