hi, just looking for some advice or people to talk to who may be going through similar… i discovered a hard lump in my neck just behind my ear slightly further down, i went to the GP and he said it is a lymph node and to give it a few weeks he described it has hard but not rock solid and he said it seems smooth and moveable. i decided to go back about 3 days after that appointment due to constant itching which is sending me crazy… he decided to do me a full blood check on friday to see if theres anything going on with that, just wondering if it does come back normal is that likely that its nothing serious ? i do suffer with health anxiety so terribly worried this is something like lymphoma . i have also had such bad joint and body aches literally every joint in my body is hurting from collar bones to my finger joints , looking for any type of advice 
thank you
