<s>[INST] I would like to know a couple questions I had pneumonia and it caused fluid to get around my heart I had a 20% heart. When I went back to the dr I had a 55%heart.i feel I have fluid around my heart again in my upper side the left side I take water pills to keep the fluids down ,every time I go to the hospital its over fluids . My upper left side hurts me so bad I can t do anything even standing or a sudden movement it like kills me a.Do you have any suggestions? [/INST] Hello, I have gone through your question. Actually I need your detailed echo report and other investigations to guide you properly. But I presume that you had pericardial effusion with reduced ejection fraction (20%). This could be due to viral per and myocarditis secondary to pneumonia. This may be self limiting condition as u mentioned that now EF is 55%.in that case you will recover in due course of time. Any possibility other than this needs further work up. My best wishes DT. Teli, MD </s>
