hospitalized 2 wks ago and was given intravenous antibiotics and fluids for 5days. my blood pressure which has always been normal suddenly was extremly low and stayed low for a couple of days...thus the force fluids. The doctor at the hospital told me that echo cardiogram looked good and abdominal CT looked good, but I had hundreds of small nodules in my lungs and he said it wasn't cancer...blood work numerous no cancer. Diag final with possible COPD, urinary tract infection, and baterial ecoli infection. How do I treat or rid of these nodules?
