I am 19 years old. I had a bladder infection for 2 weeks and I thought it went away about a week ago. But on Thursday I started getting pains in my bladder and I blacked out in the shower. Since Thursday I have had nausea but haven't thrown up at all. Im also dizzy most of the time. Whenever I sit down my crotch hurts. I have to pee a lot. It doesnt hurt to pee anymore so I dont think its a bladder infection. What could be wrong?
