I have had a UTI for 2 months, this is my 2nd antibiotic. The other one calmed my symptoms and reduced the burning and the need to pee but then it came back after about 2 weeks. I am now on 100mg of Nitro and have been for only 2 days and I am getting almost all of these symptoms. I have a headache, severe nausea, every time I use the restroom I have diarrhea, stomach pain, chills, and all of my muscles are aching like I have just been in a car accident. I feel miserable and after reading all the post here - I am calling my doctor for another drug.
