My 21 month old daughter has had a fever for the past 2 days accompanied by a painful swollen gland on the left side of her neck that we noticed yesterday evening. We took her to the ER today and they did a cursory check-up and gave her a diagnosis of adenitis, saying that it may be a viral infection and swollen lymph nodes, along with advice to follow-up with her pediatrician tomorrow. They recommended giving her motrin and tylenol concurrently for the fever and the pain. As the day has progressed we've also noted a rash developing on her feet and slowly coming out on her hands as I type this. As I've looked online I've seen several possibilities (some ok and some not so ok). We spoke with a family member who is a physician and they believed it could be hand foot and mouth disease. I'm just wondering if anyone else has seen similar symptoms in their infant and can give some advice to/shed some light for before we visit the pediatrician tomorrow.
