Help!

Shelby
I am 25 weeks tomorrow. I was in the hospital two weeks ago with a raging urinary tract infection. I was put on antibiotics which I thought got rid of the infection until tonight. I used the bathroom and now I feel miserable. My bladder is throbbing, the pain is extreme and it is very uncomfortable. Has anyone experienced frequent urinary tract infections while pregnant? Does anyone have any remedies? I really don't want to go back to the hospital tonight but if I can't get this feeling to subside or go away I won't be getting any sleep tonight. I am miserable :(
