The culture was taken before I was on the last antibiotic. So, I'm really confused. I took Pyridium tonight and it didn't help. I still felt an urgency when I was out. I think I just have to get used to this for awhile. I'm happy that I have no infection. But I've never had anythiing like this before. It's like the symptoms won't go away. Check out the thread entitled.."What's Wrong With Me? Chronic Constant UTI symptoms"...There were a lot of people on that who are like us. Plagued with symptoms that won't go away. I explained the red thing to the nurse. She didn't seem that concerned. I go back next week. Sorry about having to sit through that concert.
