I am a male, 62 years old. I have a nagging backache, not to painful - but I know it s there, on my lower left side. I am under treatment for an enlarged prostate for about 8 months. My erectile dysfunction has been prevalent over the past two weeks. My urine does not stink or appear to have blood in it. I do feel sluggish during the day and I usually get up to urinate about three times nightly. I am in good physical shape, riding my recumbent stationary bike four or more times a week for thirty minutes each time and lifting weights about three times a week, on average (I can bench press 200 lbs) and I play golf one or two times weekly.
