I have a history of kidney stones (Calcium Oscillate) (14) to date every 3-4 years. I am 63 years old. I passed a couple of small granular ones a couple of days ago. I was fine for one day. Played some basketball for 2 hours and was fine for about 24 hours then my urine was slightly pale pink at the beginning of urination with slight difficulty and then cleared up. This occurred for about 2 days then all the symptoms disappeared. Today the slight pink appeared at the beginning of urination. In the past my doctor prescribed Flomax and everything cleared up. What do you suggest I do at this point.
