I can feel small lymph node in my neck the doctor said its 9m is this normal.iam itlle worry.but the rest of the lymph node i can't feel them.

Lymph nodes: Lymphadenitis or swollen lymph nodes is due to viral or bacterial infection. The swollen lymph nodes caused by cancer is not very common condition. I don't think that your case is any different. Possible a dental infection due to tooth abscess, gum abscess or combination of both. A sore throat is another option. Rec.: see another physician or dentist for the second opinion. Good luck.
