I'm really worried about the free fluid in both pleural cavities on the imaging scan we got back. They measured around 500ml on the right and 300ml on the left. How serious is this situation, and what should we be doing about it? Can you please let me know soon? I'm really anxious about it.

This condition is known as pleural effusion. To help reduce the fluid buildup and relieve symptoms, you can take diuretics like Furosemide. Additionally, a medication called Spironolactone can also be prescribed to help with fluid retention. It is important to follow up with your healthcare provider for further evaluation and management.
