### Patient: Doctor, I've been experiencing drainage in my throat, shortness of breath, drug abuse, rib pain, and difficulty breathing, what could be the cause of these symptoms?
### Doctor: Based on your symptoms, it's possible that you have pneumothorax. This is a condition where there is air in the space between the lung and the chest wall, causing the lung to collapse and resulting in symptoms such as rib pain and difficulty breathing. The drug abuse may have contributed to the development of pneumothorax as well.
