It is possible to have a partial or complete lung collapse. Sometimes a partial collapse might affect just a small part of the lung, and you may only have mild symptoms, or may even feel nothing. A very small lung collapse may heal on its own, but it is very important to see a doctor if you think you have a collapsed lung.

Some symptoms of a collapsed lung are:

• Sharp stabbing pain on one side of the chest;
• The pain is made worse by breathing in;
• Difficulty breathing/breathlessness;

If you have these symptoms, it is important you get medical attention as soon as possible, preferably from an Emergency Department at a hospital. Here, the doctors will be able to see if your lung has collapsed and will be able to give you appropriate treatment.

We recommend talking to your usual doctor in advance about what you should do if you think you are having a pneumothorax, so you are prepared to act appropriately.
