the UTI got worse before it got better. I hadn't had one in probably 5 years, and I don't remember it being like this. It wasn't the most painful thing I have ever endured, but the bladder spasms were about every 30 seconds for most of the day. That sort of thing is exhausting. And my kidney hurt for a good portion of the day. The antibiotics are really helping, and I took some aleve, but I'm glad that the pain is gone.
