Lump on collarbone?

[MumOfHals]

I've got a collarbone lymph node that I've had for years, I've had my flu vaccine as pregnant 2 days ago and I've noticed it's tripped in size.

Anyone else had something similar? I'm worried its lymphoma

It’s most probably the effect of the flu jab. I’d leave it completely alone for a couple of days, then check it.
