I am a 45 year old male, and over the weekend, I started to experience brief, but sharp pains (like a knife) on the left side of my pelvic/groin region. They lasted only a second or two and would occur about once an hour for the first day. Over the past two days, the frequency has dropped off, but they still hit me once or twice a day.
My guess is some sort of kidney stone moving down my lower uterer, but I have had no back or flank pain, and my urine appears normal.
Not much pain since the weekend, and I haven't passed anything that I know of, though I have been drinking more water than normal. I do have a history of unexplained hematuria (have done the IVP and scopes twice a piece over the years). I just don't know of anything else in that area (in a male) that could be the cause of that sharp a pain other than a ureter (or perhaps a pinched nerve).
Does the stone only cause pain when it's moving in the ureter? And how long does it normally take to pass a stone once it begins to travel down the ureter?
