my dad is 63 has a lot of health problems. hw just got released from the hospital 1 day ago. He was in there because his body retains fuild and they were trying to get the fuild off his chest and lungs. But they were taking it off so fast that it was interfering with his kidneys and bladder. SO they stopped, and sent him home. Now he is having fuild coming out of the pores of his body (feet, legs, arms, everywhere) What is causing this
