Hi there,

I've had a small rubbery moveable lump on the left side of my neck for as long as I can remmeber (last 7/8 years). It's size is slightly larger than pea sized but smaller than a 1 pence in size (a couple cm I would say). It has never changed in size and it's not visible at all on my neck as it's deeper under skin. 

I've never had it checked because I am only 22 and first noticed it when I was much younger. I didn't think much of it. It's always there and I rarely notice it but recently, having more awareness of lumps/cancer - when I do notice it I get worried. It is painless and I've had it for years and years so it's probably nothing to be worried about but should I get it checked anyway? 
 

I don't have any persistent symptoms other than abdominal pain related to my periods and tiredness which I think could be related to a vitamin deficiency or something.
 

Any advice appreciated!
