I was to the docter yesterday and was running a fever 102 for a bladder infection. Because of my other medications He put me on ciprofloxacin Hcl 500 mg. I woke up freezing but didn't get up but around 5 am I was burning up it was 103. I've briefly had heart papitaions. He said I should be feeing better but all I have been doing is a lot of sleeping, now I've start to ache in my vaginal area.
