OMG Catrin! I had the same thing. I was positive I had appendicitis. Friday the doctor calls with test results, all blood work was fine, but my urinalysis showed a possible UTI. It won't be confirmed until Monday, when they get the culture results. She started me on antibiotics, and after two days, I feel pretty darn good.

I hadn't connected the back pain to it, until I realized this morning that it's gone. I'm not sure how long I've been living with this, I think the back pain has been going on for about a month.
