Any nurses or anything on here?

So I have been having flank pain for a few weeks. Went to urgent care tested for a uti and everything was normal. Got an ultrasound of my kidneys, again normal. All while having to pee again 10 minutes after I pee. This was my past few weeks. So today I have been having the flank pain along with not being able to pee. I can dribble a little but that is it. I have been drinking water but I have to pee but can’t so I went to urgent care tonight and they got a dribble and said no uti. He gave me an antibiotic for one anyways. I still can barely pee and I have to go! It hurts bc my bladder is full but still only a little dribble comes out. Has anyone ever experienced anything like this and can help a girl out? Any advice would be appreciated. Also, There is no chance I’m pregnant. Thank you in advance!
