The dreaded UTI

Hi ladies! I have unfortunately got a UTI this week. Yesterday is when I started noticeing symptoms and today its in full swing. I have to get a urine test today and then they will release antibiotics to me to pick up. In the meantime, Im hurting like heck. Has anyone tried AZO? Im desperate. I have been drinking tons of water, trying not to hold my pee, and going to pick up some cranberry juice. Im just scared the processing of my urine will take awhile and I dont have time for that when it feels like lava when I pee. Thanks!
