I had flickular lymphoma before and did retuxin. That was 3 years ago. Now I have a swollen lymph node in my neck next to my ear, and really tired.

Recurrence? You need to call your oncologist. If it is a recurrence, Rituximab can work again. Could be unrelated to your lymphoma but you should still call your oncologist.
Need an evaluation. Thus could be rrlated to an infection but follicular lymphoma can return. You should follow up with your oncologist.
