can you have a sever kidney infection without a fever? I have chills and several of the other symptoms including lower back and abdomen pains, loss of appetite, nausea sometimes vomiting, neck pains and a severe headache, I pee a lot every few minutes and I have little to no energy and usually when standing or walking I have moments of blurred vision or partial blindness, I have serious vertigo and moments where it feels like I'm about to pass out up to a total visual black out, this last one happens suddenly and I try to sit as soon as possible.
