Hey, I have an enlarged lymph nodes on both sides of my jaw. I've had them for 2 years and they have never changed and they are just below half an inch in size. I also got them scanned by a doctor 2 years ago and they appeared to be fine. I also have no cause for them to be there. They may just be there because I’m slim. I have started to get light headed when I raise my head too fast and I'm scared incase I might have Waldenström macroglobulinaemia since I have light heads and 2 raised lymph nodes. I've went to the doctor 2 years ago to get the node scanned and the results came back fine but I still don't have a cause for the lymph nodes being there. I've been told that my lymph nodes may be non cancerous since they haven't changed for over 2 years but could I still have Waldenström macroglobulinaemia with an unchanged lymph node for that amount of time? I’ve been told that if a lymph node remains unchanged for 2 years it isn’t cancerous so would it still be possible for my to have Waldenström macroglobulinaemia and if yes how so? I am also only 17.
