Hi @ahmg. It sounds like you have a little mystery going on with the swollen lymph nodes. You’re doing all the right things in having this looked into to see if there’s any reason for concern.

You mentioned having a consistently low white blood count. Do you recall if the blood work you’ve had done was a CBC or was it a CBC with Differential?
The differential will define each of the 5 types of white blood cells. With lower counts, especially neutrophils and lymphocytes, your body will have a more difficult time fighting off infections. It can take some sleuthing to get to the ‘why’ it’s low though. Sometimes it’s an underlying inflammation or fighting an infection. And yes, there can other causes. It’s too premature to jump to lymphoma but it is good to be proactive. You’d like answers so that you can let this go…

Your doctor did check for inflammation with the ESR and viral panels. CRP or C-reactive protein test can be useful too.
Another suggestion is to have a biopsy of the lymph nodes. Do you have swollen nodes anywhere else? Has your doctor suggested a biopsy of the lymph nodes?
