High WBC, lymph nodes swollen for 2 months but no fever - infection or cancer?

[Camachameleon]

I went to the university campus doctor because the lymph nodes in my neck have been swollen and tender since late January and now the ones under my arms have started to swell. I also have been majorly fatigued/weak the entire semester and my arms/legs will randomly start tingling and my nails will turn blue. Also, I've been getting extreme aches in my legs, like I have the flu or something (I don't). The Dr tested for mono (it was negative), CBC, Sed rate, and C-Reactive Protein. My WBC was 12.0 - Neutrophils were 8.6 (72.1%), Lymphocytes were 2.3 (19.2%), and the other ones were at normal levels. Also, I have low MCH, MCHC, and MCV. My sedimentation rate was flagged as high, as was my C-Reactive Protein (7.5). I never get fevers even when super sick, and I don't have one now. Also, I've lost 10lbs since December and I keep getting a weird skin rash (red circles?) that doesn't go away with antibiotics or antifungals. It's not itchy and the spots come and go randomly. Three days ago I started feeling so nauseous and weak that I couldn't stand up for almost 10 minutes and I couldn't feel my hands.
These are really strange symptoms and I don't even know if they are related but they all got worse around the same time, though, so maybe. You'd think with the numb hands and fatigue/weakness that it would be anemia but my CBC says all that stuff is fine. My main question is - does this sound like some sort of virus/bacterial infection, or leukemia/lymphoma? I've been googling all my lab results and I'm getting a little freaked out.

Hi, it seems like an immune reaction -- whether to some infection or instead an immune system gone awry.

Numb hands? My first thought was something related to Raynaud's Syndrome. Rashes can be from mast cells, and so can being light headed, and also pronounced GI problems.

If you get dizzy when first standing, that's likely
'orthostatic hypotension'. See if your pulse goes way up then to compensate. Also be sure that your pulse is not irregular then.

Yes, everything is likely related. Do you or your family have any past history of odd immune episodes or conditions?
