Cbc normal but lymph nodes swelling in neck and one behind neck also had one last year on elbow and nothing came of it.?
See a doctor. Hmm. Lymph nodes can swell when your immune system is fighting an infection. They are usually tender when that occurs. A viral infection like "mono" can cause the lymph nodes in the back of your neck to swell. Certain cancers can also cause lymph node swelling. This would not show up on a cbc. A doctor needs to feel your nodes and decide if further tests are needed!
Possible malignancy. Lymphpma or hodgkins disease or aids could present like this. Wbc does not have to be abnormal. You need full exam, lab studies, and possible node biopsy.
