bladder infection
"After taking 2 pills I suddenly experienced chills and fever of 101, and a severe throbbing headache . I called the dr, spoke to the nurse she advised to continue taking . My gut told me not to, later in the evening I developed tingly fingers . I called my dr and he said stop taking I may be having a serum reaction. It's been over 24 hours since I have taken macrobid and still have terrible throbbing headache , upper back ache , and low grade fever.  This medication is poison !!!  I can't believe it hasn't been banned ! Will pass the word to everyone never to take this horrible drug !"
