What Causes Burning Sensation In Clitoris And Foul Smelling Urine?

Hi.. I suddenly had a change in urine odor and appearance.. It now smells strong, like ammonia almost, and is very cloudy and bubbly.. It goes away if i drink a lot of water but it still worries me.. On top of that, there is an on-and-off burning and stinging pain in my clitoris.. Just now, i felt some tiny pricking sensations that are the same as how my dad described passing stones when he had a kidney stone problem years ago, and so i m very much scared right now.. I thank you in advance for all your help..
