I am a generally healthy 52 year old female. Last week I was diagnosed with a 5mm kidney stone and was prescribed Flomax to help pass the stone. I passed it about three days later and now I am wondering if I can stop taking Flomax. The urologist said I would have to take it for a month then have a follow up ultrasound to make sure I don't have hydronephrosis. I find the side effects I'm experiencing (headaches, stuffy nose and nose bleed) very annoying.
