Hi all, I was wondering if anyone would be able to shed some light on my current situation...

I have a small lump on the right side of my neck, just above my collar bone. It does hurt, it is the size of a little pea and it moves a small amount under my skin. I noticed it around 2 weeks ago - it's hasn't really changed during this time. 

I am also shattered..all the time! Like really tired and have been struggling to do normal day to day stuff because im so tired! This has been for about 6 weeks. 

Ive googled all this (foolishly) and now im concerned it may be lymphoma. 
 

am I totally barking up the wrong tree or am I right to be concerned? 
 

thanks you guys.
