urinary tract infection
"This antibiotic is a God send! I am allergic to Penicillins and Sulfas. At first I tried Cipro, it didn't work. I had kidney stones for 8 months, I finally got my second lithotripsy in June for an 8x9mm stone and then my kidney got infected. This is my fourth day on Macrobid and I have had no serious side effects except 1 bout of diarrhea on day 1, which was welcomed compared to the nausea and pain from the infection. Macrobid actually got rid of my nausea!"
