I have problems urinating. It's hard to start, weak flow, can't empty the bladder. This started 3 days ago. I went to the doctor today and they took a urine test but don't know the results. They gave me a 10 day supply of antibiotics. I drank a lot of water and cranberry juice. So could this be a kidney problem because I have had prostate problems most of my life and I have never had anything like this and I'm 62 years old.
