Tiny stone symptoms and conditions

I am a 52 yr old woman who was rushed by ambulance to the hospital on Sunday 4, 2009. I awaken with a horrible ripping pain in my lower left side and back. It reminded me of labor pain although it was worse because I knew I wasn't about to have a baby. I could barely walk and the pain kept me bent over, and burning in agony. After being x-rayed and diagnosed I was told I had a very tiny kidney stone, along with a UTI. I was told they could manage my pain better if they kept me overnight, with hopes I'd pass the tiny stone by urinating in a little strainer cup, to catch the stone. I've not seen the stone yet, and this is the 3rd day. Anyway, I awaken in the hospital after being knocked out by pain medication, with an excruciating headache, as if someone was putting pressure on my neck and back of head. I also noticed a big red rash on my forehead. The nurse gave me benadryl, and continued my doses of Bactrim, and Flomax. When I was released the next day I was given a prescription to fill, Bactrim 2X 3 day therapy, Flomax, and Vicodin. Recovering at home I've had an excrutiating headache the entire 3 days.. I had nausea, felt chills, had no appetite, and felt dizzy and as if I'd throw up every time I got up. I ran a low grade fever of 100*. After reading this site I know that it had to be the Bactrim that caused all those horrendous side effects.This is the fourth day since I was diagnosed and I still have a UTI, and will be calling my doctor in the morning, thanks to post like these.
