What are these lumps on my neck? Only my right side of my throat hurts and 3 days into my illness I noticed a nickel sized lump.

Lymph nodes. Very likely they are lymph nodes. These glands are the regional headquarters of the soldiers of your immune system when they are fighting an infection. They tend to enlarge when there is an increased demand of fighter cells in the affected body part. Head and throat infections tend to cause lymph node enlargement in the neck region.
