Neck Lump

[kingorange91]

Hello all! So around august last year, I discovered a lump around the size of a nickel underneath the right side of my jaw. It doesn't protrude from the area, rather I need to puff out my throat to be able to feel it. At first I thought nothing of it and thought it was just an enlarged node as I compared it to the other side and it is relatively biggerIt's been almost one year, and it has still remained there, no change in shape and size. I only looked up what the causes and symptoms are recently around march. Of course when you start looking at symptoms, you start "exhibiting" them. I haven't been exhibiting any symptoms consistently, but flu season is about to start and I've noticed that there are small bare legs flashes of pain around the area. I was just wondering if anyone can enlighten me on this.

Background:
Noticed lump in neck august 2016.

No change in size since then.

I smoke around half a pack a day.

I have (according to my dentist) poor dental hygiene.

I had a root canal November last week for an abscess tooth (however it was on the left side of my mouth.

I had a cyst removed right beneath my chin (size of a quarter) in 2011, which turned out to be non-cancerous.

My brother had a cyst removed from his shoulder which can only be found in Caucasian genes (don't know how this is related but it might be.)

All insights/experiences are appreciated! thank you!
