it started 4 nights ago , I woke up with chills and fever..i was already on a antibiotic for a slight uti..now I have severe neck, lower back, leg and even feet pain,,I cant even walk when i first get up, I went to Doctor , had a ua done ..it only showed slight infection .I got a shot of Rocefin the next i woke up the same all over pain..went back to doctor and started on another antibiotic..It's strange because i am never sick...
