My husband has a 3 mm. stone, had an attack 5 weeks ago (went to ER) and has been on Cipro (for infection), Flomax & Valium since....He has felt it move down his back with since then with no extreme pain, just dull & achy. Now he says he can feel something sharp in his penis. He says it hurts, he has burning & urgency to urinate. Does this mean he may be finally getting ready to pass it?
