You have a pleural effusion. This means you have fluid in the space between your lung and your chest wall. This condition may result from many different problems including:
Pleurisy or inflammation of the lining of the lung.
Lung infections such as pneumonia.
Blood clots, heart disease, chest injuries, cancer, and other medical problems.
A pleural effusion may not cause any symptoms. If it is large, however, it can make you short of breath. Other symptoms include cough, chest pain, or fever. The diagnosis of a pleural effusion is most often made by chest X-ray, CT, or ultrasound studies. A sample of the fluid can be taken using local anesthetic and a needle or catheter placed between the ribs. This procedure may be needed to determine the cause of the effusion, or to treat a large effusion.
Treatment is specific to the cause, such as antibiotics for infections. Mild pain or anti-inflammatory medicines may be helpful in relieving symptoms. Chronic effusions often have to be periodically drained. It is very important that you see your doctor or a specialist to be sure the effusion is not from a serious medical condition. A follow-up chest X-ray is usually needed.
SEEK IMMEDIATE MEDICAL CARE IF:
You develop shortness of breath.
You develop increased pain.
You develop a high fever.
