Hoping someone can provide some insight into what is causing my 19 month old son to suffer from 3 plus weeks of fevers, some very high. We’ve been to the emergency room twice, 3 overnight hospital stays and still no answers. Initially we were told it was a virus, or more than one virus but it seems unlikely a virus is causing the extended fevers. Besides the fever, he’s had a couple days where he had a rash, mostly on his legs, but on his arms and face as well. Since he isn’t talking yet, we don’t know what else is bothering him. The doctors ruled out bacterial infections. His WBC is hovering around 20K, his platelets are high, and his SED and ESR (I believe those are the acronyms) are also high. An ultrasound of his abdomen didn’t reveal anything. We have an appointment on Thursday with a rheumatologist to determine if he has an auto immune disease. But my wife and I are going crazy with worry. I’m hoping someone might have suggestions for things to look into while we wait for the doctors to see him. Thank you!
