urinary tract infection
"I was prescribed Macrobid the same day my UTI symptoms began, by my visit to the clinic it was already very painful. By the second day my uti was slightly better, the dizziness and nausea was intense but it didn't impede my ability to function. This continued until the fourth or fifth day when the headaches began, first they were manageable, but after dose 10 I wasn't able to function without getting sick (By then the UTI symptoms were almost completely gone). The side effects lasted until all the medication was taken and for a couple days after. That being said I've always been very sensitive to side effects from medications and everyone's body will react differently. Take with food and lots of water and the whole ordeal will be over soon."
