hi I took my little boy who’s 3 to the drs I thought it was his vein popping out and showing but they said it’s a swollen lymph node and have referred him to the hospital is this normal or should I be worried about something more serious as why would they refer him to hospital if it was nothing as I do no that sometimes they can be swollen due to infections but there’s no infection been there since 2023 and got worse he’s only just turned 3
