It's a medical condition where there's fluid accumulated between your lung and the layer surrounding it (pleura) that can be secondary to infection, malignancy, etc.

I had the same issue like 4 years ago. But unlike you I had symptoms like bad pain around my chest, unable to breath properly and high fever. They took sample from around my lung with needle and do the lab thing. Doctors told me they should operate me and remove the fluid. After that I went to Minilik hospital. They also said similar thing. But told me to have last x-ray test and after the result the doctor said it's tb and he prescribed me tb medication. I didn't believe it was tb but continued taking my med. Finally thanks to God I got cured 🙏.

What diagnosis did ur doctor tell u.???

My professional assessment would be well depends you see if it's malignant your time on earth is really shortened a year tops if its not the malignant one you still need to be hospitalized and get the underlying condition.

In addition to the one that is mentioned in the above reply, it can be also due to the accumulation of air and the fluid could also be a blood. Its could be caused by Heart failure, nephrotic syndrom hypoalbunemia blunt or penetrating chest injury and yemesaselut Managmentu demo intercoastal drainage yhonal malet new betkitu
