Wow, that's really good how you posted the CBC like that. Very helpful.
The thing to notice is that, while a blood cancer can suppress neuts, it wouldn't happen at all so quickly. Also, lymphoma nodes are almost never painful.
But a virus can make lymphocytes high and neutrophils low - and also cause painful nodes.
Your CBC likely just shows residual effects from the virus.. plus stress which activates hormones like cortisol can also affect things. I wouldn't worry.
