Lymph Node Problems?

The fact that the nodes feel movable is good. Lymphoma typically causes hard, enlarged, fixed nodes. Are you taking allergy medications? Decongestants? Sinus problems can become chronic and last for months. If you've been tested for lymphoma, I wouldn't worry. If the 4 physicians you've seen weren't able to give you any answers or make the node shrink again, you should see another doctor. You shouldn't have nodes enlarged for so long without relief (even if its the proper sinus/allergy medication)
