Itchy lymph nodes? Should I be concerned?

Hi everyone,

So I've had a very slightly enlarged lymph node on the back of my neck since I was around 21 (I'm 30 now!). When it got enlarged I pointed it out to my GP who wasn't concerned. It really itched at the time but stopped for a while. For the last few months it's been really itching again, but a lot more than it used to and weirdly much worse if I drink a glass of wine. I dont have any other symptoms, just an enlarged and it by lymph node. Anyone who has had lymphoma, did it start like this or should I not worry about it? Just don't want to sound like a numpty to my GP saying I've got a bit of an itch on my neck!
