I was prescribed metronidazole due to a slight bacterial vaginal infection. I was told I have to take it 2x a day for 7 days. I took my first pill this morning and a couple of hours ago, I urinated for the first time and experienced a burning sensation right after urinating. I also started to feel the urge right after that and a continuous pain in my urinary region even while not using the restroom. Ive had a UTI before and this is exactly what it felt like. The same day I was prescribed the meds, the tested my urine and said there was no UTI, which was about 5 days ago. Is it possible that this is a side effect from the drug?
