I have a friend in town with MS. She had a UTI and didn't know it. Over the summer she ended up in a major flare and in the hospital only to find out she had a UTI and that caused her flare.
Don't worry Deb, I get the same remark when I go to the neuro. And, since they don't do any testing or ordering of testing for a UTI, I now go to my PCP 1st to rule out any kind of infection.
I hope you start feeling better soon.
