Hey, I've had swollen submental, submandibular and cervical lymph nodes for 2 years. On both sides. They’ve never changed and they are all below half an inch in size, non tender and moveable. I'm also very slim so that may me why I can feel my cervical and submental nodes. I can also only feel the nodes when I dig for them. I've also never experienced any symptoms of lymphoma. Could these be permanently enlarged due to and old oral or dental infection? I have been googling it and Google suggests that it's lymphoma since the lymph nodes have be swollen for so long. What else could this perhaps be or what other problems can cause a lymph node to remain enlarged for so long because my anxiety is really bad especially since I've been reading that this may be cancer...
