<s>[INST] Hi doctor, I have recently visited ER due to sob. Then, I was diagnosed with a pleural effusion of left lung. Blood work and urinalysis completed during the visit showed normal values. I had chest x-ray and CT scan, which confirmed such and revealed a mass in this area. I went to medical center the next day for pleural fluid drainage and subsequent sample analysis. The sample results from fluid were clear and the drainage helped with breathing. I just returned from the medical center following the biopsy of that area. My radiologist indicated that the biopsy area was more shallow than he has experienced with other patients. I would appreciate your thoughts. I am currently on Lopressor and Losartan. I had not experienced breathing issue prior to this and it recently occurred just two weeks ago. [/INST] Hi. For further information consult a pulmonologist online --> </s>
