Just wondering whether worrying about lymph nodes is really common amongsthealthanxiety sufferers. I first noticed a lump in back of my neck about 15 months ago and had blood test that came back clear. I then didn't worry too much until about 6 weeks ago when I found second node on my neck. Since then I've become obsessed again even though both lumps are less than 1cm. Waitineg for result of another blood test but won't b happy even if they come back clear as have read so much about lymphoma not showing in blood tests :-(
