Hi everyone ,

please help me .I am so worried and constantly thinking I'm going to die soon. Googling isn't helping either but I have serious health anxiety and can't stop myself from googling things .

I have had these swollen lymph nodes in the submandibular area (under my jaw) for about 6 months now.Note that I canotactdy GP earlier 3 weeks after I discovered these nodes. He referred me for an ultrasound but it came back clear .I was told that they're just reactive lymph nodes. Although they did go down a bit after the ultrasound, they're still there ...it's been 6pm that now and they haven't fully gone down.You can't see it but can be felt when I lean my chin on my chest and feel under my jaws .Also, my wisdom teeth has been coming out and I've had some pain in both sides of my teeth where the teeth is coming out for 6 months now so since the ultrasound came back clear , I was blaming the swollen nodes on the wisdom teeht .

and then all of a sudden , I was experiencing some very Sever neck pain , I took some naproxen and the pain completely disappeared but it left another small lump on the back of my neck .I thought it was a muscle knot but it's been two weeks now and it's still there . I also found another hard lump at the back of my head 2 weeks ago. It's not movable but also not growing .and recently, my blood tests were showing high b12 levels .My doctor doesn't seem worried about the high b12 .He referred me to an haemotologist who isn't worried either .: these swollen nodes are the only symptoms I have .No night sweats, no fever, no tiredness .No other symptoms at all but I'm dead worried ! All I think about is cancer !

please help...has anyone ever had similar symptoms which turned out not to be cancer ?
