Question: My daughter is 16 years old. She had a bad kidney infection was hospitalized twice. Went through Bactrim (she had an allergy to), Levoquin & Amoxicillin (diagnosed with a strain of Ecoli). 2 weeks later she still has abdominal and lower right flank pain daily (it's not too bad most of the time, but sometimes it gets really bad). She gets nauseous and also said her heart beats really fast sometimes. Trip to the Immediate Care showed protein in the urine at 100, and also some 'particles'. She's had the particles since before her infections was diagnosed. Wondering if we should wait until next week to see her GP again, who would refer us to a nephrologist they said, or if we should go to an ER sooner. The last two trips to the ER they did ZERO ultrasounds, CT can, lower gi, anything like that--only blood and urine tests. They said she did not have bacteria in her blood. Thinking this could be kidney stones? Some type of kidney disorder? She has no fever. White cell count good. She has cheer camp 3 days a week and wonder if strenuous exercise is ok? What are your thoughts? Conflicting things to do for diet and fluids based on kidney stones vs. kidney damage/disease.
