Hi, I Have A Swollen Lymph Node Just Under My

It could be many things
Detailed Answer:
Hi Asu567,
Thank you for the elaborate history; I am sorry to hear about all that you have gone through.
First of all, the d-dimer is a very unspecific test for venous thrombosis, and if you have had elevated inflammatory markers, e.g. CRP or sedimentation rate, it will be elevated regardless, even when you do not have a thrombosis. Considering the location of the swelling, it could be a branchial cleft cyst, which is a completely benign congenital malformation. If the ultrasound showed a large lymph node, and there is no history of infection of you neck, throat, ears, etc. an extirpation of the lymph node with examination under a microscope with provide a tentative diagnosis.
Do not hesitate to contact me if you have further questions.


Also is it possible for my lymph node to be swollen for 4 months for the reaction of allergic reaction I had last year in my face and neck? Or that is also a early symptoms of lymphoma?
All is possible, however, cancer unlikely
Detailed Answer:
Hi again,
I think it is your earlier infection. Lymphoma is unlikely.
Best wishes.
