I had a Pap smear last Tuesday, which I hadn t had in 5 yrs--I am now post menopausal. On Wed and Thurs of last week, I felt a burning kind of sensation while just sitting at work and also when urinating (I sit for long periods)--I know that I was at least partially dehydrated as well. Then on Friday night I started having blood in my urine--more than just spotting--at some point I passed a small clot--I was shaking a lot at one point and could not get warm, but no fever. I had to get out of bed numerous times to void that night, which caused a stinging sensation thru out my whole body. I took Advil and went to bed and was feeling better--but only after drinking 64 ozs. of water in a short period--trying to flush things out. I was fine all Friday day and night, and now on Saturday afternoon: the bleeding has ceased but I sense that I can t completely empty my bladder and when I do so I have an uncomfortable throbbing feeling down there (I m still drinking lots of water). I m trying to hold off going to the ED but I don t want to wait too long...What do you recommend?
