I have a prostatitis with E. Coli ( 100,00 col) and have been on cipro (Sensitive) for 5 days, sympthoms are better, urine flow is better, less headache and nausea, appetite is better but I continue to feel chilled and have sort of intolerant to cold temperatures. Is this OK or should I be worried?. No fever since second day but my temp is subnormal 97 .
