I have had a UTI for close to 2 weeks now! I took a 7 day prescription of Macrobid and it did absolutely nothing. On the eigth day I went to the ER and they prescribed Levaquin. It is now 3 days later and my stomach still feels like it is going to explode! Please is this normal?? Does anyone have any advice for me! Please Help, its the worst feeling ever! Thank you.
