[/INST] there and plenty number of reasons for fluid in lungs and also in pleura. you are talking about pleura I suppose in this case.the possibilities can be cardiac function may not have reached to normal levels so might be a cause of pleural effusion as your doctor says it is not TB. They are right it might be just a body reaction to a major illness causing increased ESR because ESR is a very non specific test that can be increased in n number of conditions so its not a diagnostic test </s>
