bladder infection
"Doctor prescribed this antibiotic for me for my UTI, I must say it did take away my UTI painful urination very quickly but after a day of taking it I felt like I had the flu. I was shaking, freezing, very nauseous, bloated, had back pain and extreme gas.I actually thought I was dying.  It backed me up so bad I couldnt make a bowel movement for 4 days and had to take a laxative to get everything out of me which made me feel worse. 
I still have 2 days left of taking it but I think I'm stopping today because I'm in so much pain from this antibiotic. If your doctor prescribes this to you, ask for something else because its god awful."
