Expected Course Viral infections and minor skin infections and irritations can cause lymph nodes to double in size quickly over 2 or 3 days. They return slowly to normal size over the next 2 to 4 weeks. However, they won't disappear completely. You will always be able to see and feel nodes in most normal, healthy children, especially in the neck and groin. Don't check for lymph nodes because you can always find some normal ones.
Home Care Treat the cause of swelling.
For bacterial infections, the underlying disease that's causing the node to react needs to be treated. For example, remove the splinter, treat the ingrown toenail, or have a dentist treat the tooth abscess. Many children with swollen lymph nodes due to a skin infection also need an oral antibiotic. Pain or fever relief. For pain or fever above 102 degrees F, give the appropriate dose of acetaminophen or ibuprofen.
