Hospital says it’s probably a swollen lymph node. But she hasn’t been sick, it came out of nowhere and it’s huge! Size of her neck

Update went to a different hospital children’s Please pray for my baby because I am losing it The ultrasound came back that there were multiple swollen lymph nodes, they did a chest x-ray to check the lymph nodes and those looked okay. The blood work came back that there was there was no infection. I have to make an appointment with an infectious disease doctor for early next week, if the lymph nodes don't get smaller they're going to have to do a surgery and biopsy. If they do get smaller I stillHave to go to the appointment

UPDATE # 2

Harlow has her well check today, her Dr. brought in a surgeon and he said he’s never seen anything like it on an infant. They admitted us immediately, she has been getting blood work and IV antibiotics every 6 hours. Her cell count is high and the infection is getting stronger. Praying the antibiotic helps it go down, her dr. Came in a couple hours ago and i had asked “even if this antibiotic helps, how will we know why this happened and how will know it won’t happen again” she said they will probably do a biopsy anyways. We will be at the Cleveland clinic for a couple of days.
