From past 3 days I was having mild pain in my lower left back and flank pain with shortness of breath,fatigue and temp of 96.5.today in early morning I got up and found that my legs are feeling weak like very shivering fatigue and the lower back might be related to urine infection or
kidney stones.is 96.5 temp ok and what's causing my legs to shiver or a kind of unexplained pulling of muscles,is it anything related to muscles or how.
