urinary tract infection
"I was diagnosed with a UTI yesterday afternoon. I took my 1st dose of Nitrofurantoin 100mg twice a day for 10 days this morning at 9 a.m with toast and water. By 11 a.m. I felt really nauseous and dizzy then by 12 I was doubled over in pain from cramping in my belly and pain in my back. I finally am able to eat again at 6:30 p.m. but now I'm terrified to take a second dose at 9 tonight. Its obviously working because my UTI symptoms are gone but I feel like crap just after 1 ."
