Essbee, I had to go to the the docs for exactly the same thing yesterday! I kept going all the time on Monday, then woke up tues with pain in my right side, where my kidney should be. I had a temp and the area felt hot too. I've been put on antibiotics, and feel fine - I think that going on a drinking fliuds mission helped flush it out, but the antibiotics will make sure it clears out. Yes you do need to go in short. I'm a nurse, and I wouldn't try and treat myself at home with this. Hope you feel better soon.
