In brief: Lymph node swelling
Lymph nodes are part of your body's natural defense against both infections and foreign objects.
Around the neck and head is the most common place for them to enlarge since they help to fight colds, ear infections, sinus infections, scalp infections, and dental. Enlarged lymph nodes in the back of your head usually come from scalp infections, ear infections (sometimes just from ear rings).

In brief: Many possibilities
Generally lymph nodes enlarge when they are doing what they are supposed to be doing, which is responding to inflammation and helping to protect you.
If they are small, mobile, soft, non-tender and stay the same size they are very probably quite benign and need no further attention.

The crucial issue is: "for how long?" Most adenopathy is transient, but when it stays, enlarges, and consistency is no clue, you need to be concerned about cause: infection and cancer. Posterior neck makes me think nasopharynx. Hope yu are better, but see an ENT if it persists!
