I am a 41 year old female. A week ago I found 2 pea-size knots in the back of my neck. The dr. did blood work, which was fine, and he said it was a lymph node, but very common. Some type of viral infection. However, I am still very worried. They are not sore or tender, but still there. I go back to the dr. in 2 days. I have never had this before, and am very scared. Of course I am thinking the worst. Can anyone shed some light on this for me? Thanks!
