... burning/pain/frequency on Monday that seemed to resolve with OTC & home treatment by Wednesday. Saturday I thought I came down with the flu, fever, fatigue and indescribably horrid shaking chills that hurt my back and one leg, in episodes that would come and go. Sunday brought vomiting 104.4 fever and ER trip. I have a severe kidney infection that went to my bloodstream, requiring IV and oral antibiotics along with other IV medicines and fluids and possible permanent damage. All of which could have been prevented if I had gone to the doctor for UTI symptoms or recognized Saturday's illness for what it could be and gone earlier. Hopefully this post will help someone!
