Hi, My dad is 82 years old. He s been in and out of the hospital for fever & vomiting. He also huffs and puffs with minimal walking and is weak. He had a heart valve replacement several years ago. That has been checked and is okay. At first they said he has an infection somewhere but we can t pinpoint it and put him on anti-biotics and fluids for dehydration. He was still sick. Later they found ecoli and he s been on strong anti-biotics for 2 weeks and then for an additional 2 weeks. He currently has a urinary tract infection. My mom said there is something going on with his prostrate and thinks he will need surgery. All of this has been going on for a month. Any advice as to what may be going on? They can t seem to get him well. Could this be prostate cancer?
