My son is 6 years old. Two months ago he had a cough and cold - nothing major, but I noticed when he tilted his head to the side he had a visible lymph node appear which he’s never had before. Two months on and it’s still there, hasn’t changed size. No other symptoms. His GP wasn’t concerned but I paid privately to have an ultrasound because it was giving me great worry all day everyday. Ultrasound showed benign reactive lymph nodes - funnily the one on his left side measured larger - even though I can only see the prominent lump on the right side. I feel somewhat reassured after the results but upon seeing it again it has spiralled that fear all over again. Just wanted to know if anyone else is or has experienced the same - and to hopefully reassure that not going away is also completely normal?
