Sensation to urge. Is the problem now.

Almost 4 months backs i suddenly realised that as I drink water i need to rush to toilet. In my bladder something happens. I can't control. From a physician i consulted and got done Urine test and lower abdomen scan. As before the test i went to for urination and suddenly felt somekind of think came out like stone. And after min i went to for test and nothing resulted in it. I did homeopathic medication and It worked but the prob is i feel sensation in urthera like tingling sensation to urge and need to go to washroom this prob has not resolved totally. It stops for a week or two and then again starts tingling and sensation. A bit of Urine in urthera or sensation i feel. This is the problem now.
