Hi, there.

LK, I feel for you. Our daughter went through the same thing at 3 yrs old (kidney infection for a week, hospitalized w/high fever). She had antibiotics until 5 yo & then deflux on both sides at Hopkins. All was fine until she was 7; then rapid weight gain of 20 lbs in 5 months; episodic side pain every 4-6 weeks. I've spent the last 2 yrs dragging her from doc to doc asking "Could this be her kidneys" with a resounding NO the answer again & again. We finally got a (wrong) diagnosis of kidney stones which turned out to be calcification of the deflux implants. Our doc said it was the first time he had seen this in his patients; the first filing he found was filed literally an hour before her surgery. She has substantial constipation & possible thyroid issues now. Watch our for side pain & insist on a CT scan if nothing shows up. Bc she had normal creatinine levels, no UTIs and normal urinalyses, no other test was done. Her left kidney now looks pretty bad on CT scan & ultrasound. Good luck!
