I'm a 26 year old Caucasian male, 6'2'' 170lbs. I've been having odd urinary system symptoms. 1) Slight pain/discomfort and tightness in my lower back where my kidneys are located, predominantly on the left side. This has been going on for about a month.2) Odd rumbling/fluttering feeling where my kidney is located on the left hand side. This feels similar to a muscle twitch or rumbling from gas, however, it's been going on for about two weeks and is almost constant throughout the day.3) Discomfort in my urethra similar to when I've been diagnosed with UTI (multiple times) and when I was diagnosed with a prostate infection once. This discomfort has not correlated with urination (ie. it's not any better/worse when I urinate), although it may increase with the need to urinate.4) Seems as though I've been urinating more frequently.5) Lastly, I've had an odd pain deep in my pelvis (I think it's where my prostate would be located) when I orgasm.
