In case of HIV infection, swollen lymph nodes usually appear after 3-5 weeks of exposure, along with 5-6 other ARS symptoms. In case of true HIV infection, nodes once swollen, will not return to normal, though swelling reduces to large extent. Only your doctor can judge their enlargement correctly and accurately.
Swollen lymph node could also be due to other infection, therefore their enlargement is not a valid indication of HIV. Further it is very unlikely that such HIV related symptoms (ARS) surface after that long.
