Four weeks ago I found a hard moveable lump on the left side of my neck which I later found out was a superclavical lymph node, I had bloods taken which all came back fine. However since then a further three have appeared, two of them in my hair line which are small but rock solid and dont move, the other one is similar to the first one but not as big and on the other side of my neck. I've recently had facial numbness and a pain in my left arm similar to that when you knock your funny bone. 

Has anyone had anything similar that hasnt turned out to be lymphoma. My mum died of lymphoma so this disease petrified me
