I understand your frustration with your UTI. I have spina bifida and have dealt with these things my entire life. I am frequently on antibiotics, which mess up my "stomach" and make me feel awful. Macrobid (Nitrofur) is usually a pretty good antibiotic. If you still feel ill though you definitely need to see the dr. when your pills are gone. D-Mannose is good but it only works if your infection is caused by e-coli. It won't work for other bacteria, and it is usually used for prevention. I have been on 5 different antibiotics in the last 6 months, and getting really frustrated and ticked off as well. Watch what you are eating also- some foods like grapes, caffeine, carbonated beverages, chocolate etc can irritate your bladder. You can research this online. Also make sure you are drinking a lot of water- 8 to 10 glasses a day.
