urinary tract infection
"I only gave it a 7 because I'm on day 3. Dizziness and nausea, be careful driving before you get a feel for what your reaction will be. Everyone is different. The nausea was often minimized by eating  decent meal with the meds, BUT it still came back about an hr to 1.5 hrs. The dizziness, I felt like I was drinking, seriously. Hopefully it's all clear when I'm done in 2 days. I was feeling like crap, I wore a T-shirt that I wear to sleep to my evening class today (I'm over 27). Glad I found this site!

If you're a female, ensure you don't have Bacterial Vaginitis (bv) because that should be treated as well."
