Just posting to see if anyone has had similar my 14 year old noticed a little lump on his upper arm, about 3 weeks ago, we went to GP who said swollen lymph node, he had just had a cold appear aswell, she said probably the cause, its been 3 weeks and its still there not bigger but still there, probably size of a pea, we have a follow up appointment on monday, im just getting concerned, weird place for a swollen lymph node to even be in the first place, has anyone else had anything similar?
