Sharon is right!
Yes it's true; you are more likely nervous for no reason whatsoever. While a UTI is always something to be concerned about and give immediate attention to, it does NOT immediately correlate to an infected joint. There are no studies that show a relationship like this. Most medical personnel err on the side of caution and obviously want to get any bacterial infection resolved quickly and completely. So, I'm glad you got to the doctor quickly when you weren't feeling up to par. Even though you usually have symptoms, it's not a given that you always will have them with a UTI. We women must be ever watchful for urinary tract infections...it's the curse of the fairer sex!!!
